Best Shopify apps for footwear and shoe stores in 2026, ordered by review count

Short answer: a shoe store loses money at two points, sizing and colourways. Kiwi Size Chart and Recommender handles the first at 4.8 stars across 1,085 reviews, and Rubik Variant Images, built by Craftshift, assigns a separate image set to every colourway so the gallery filters. Free to install, 5.0 stars across 410 reviews.

Footwear is the hardest ordinary catalogue on Shopify. Not because the products are complicated, but because of the shape of the data. A single running shoe might come in eight colourways, twelve UK sizes and three widths. That is three option types, which is Shopify’s ceiling, and you have not yet added anything else. The variant count runs into the hundreds for one product, and the store has hundreds of products.

Then the returns. Apparel returns are a fit problem; footwear returns are a fit problem with a decimal point. Half a size in the wrong direction and the shoe comes back, and it comes back having been worn indoors on a carpet, which you now have to inspect. So the apps that matter for a shoe store are not the fashionable ones. They are the boring ones that reduce size guessing and stop people buying the wrong colour.

Disclosure: we build Shopify apps ourselves. Craftshift makes Rubik Variant Images and Rubik Combined Listings, and one of them appears below at the position the App Store’s own review count puts it, flagged as ours. Five apps in this list have a longer track record than we do. Where one of them is the better buy for your store, we say so in its section.

How this list is ordered

By Shopify App Store review count, highest first. We sell into this category, so a ranking we authored ourselves would be worth exactly nothing to you. Review count is a public number you can check in ten seconds. Every rating, count and price here was read off the live listing in July 2026, and they move, so verify before you commit a card.

Why footwear catalogues break

Two structural facts, and both bite. First, Shopify gives you three option types per product. Colour, size, width, and the budget is spent. Add a material or a fit and something has to go, which is why so many shoe brands quietly split the same shoe into several products and end up with a collection page showing the same trainer six times.

Second, only one image can be featured per variant. So a shopper who taps the Bone colourway sees one bone photo, then scrolls past forty photographs of the black, the navy and the olive to find the sole detail they actually wanted. Every product shot you paid for is on the page. Almost none of it is being shown to the right person at the right moment. Our breakdown of Shopify variant limits covers the counting side, and the free variant calculator will do the multiplication for your own size and width run.

Reordering a gallery by hand is realistic for one shoe. At two hundred styles with eight colourways each, that is 1,600 image assignments that you redo every drop, which is exactly why an app that filters the gallery to the selected colourway and hides the rest is worth its monthly fee. Free to install, 5.0 stars across 410 reviews, and yes, we build that one.

Loox Product Reviews: 4.9 stars, 8,800 reviews

The largest install base in this list, and for shoes the photos are the point. A customer photograph of a trainer on an actual foot, with a line saying they went half a size up, does more for the next shopper than any measurement table you will ever build. Loox does video too, which suits anything where the flex of the sole matters.

The concession: its cheapest paid tier is $49.99/month, the highest floor of anything here except Fit Quiz. Judge.me does the same core job from $15, and we cover that trade-off in our review app roundup. If budget is tight, start there instead.

STOQ Preorder and Back In Stock: 5.0 stars, 3,424 reviews

Footwear sells out unevenly. You will be fully stocked in every size except the two that everybody wears, and those are the two the shopper wanted. A back-in-stock alert on a specific size and width turns a lost session into an email address, and preorders let you sell the incoming shipment before it lands. Free tier available, paid from $10/month.

Where it stops: it notifies, it does not merchandise. If sold-out sizes are still visible and still clickable in your variant picker, shoppers keep hitting a dead end before the alert ever appears. Fix the picker first, then add the alerts.

Kiwi Size Chart and Recommender: 4.8 stars, 1,085 reviews

If you buy one app off this page and you sell shoes, buy a sizing app, and Kiwi has the deepest track record of them. Charts can be imported from images, product descriptions or CSV, applied per product or per collection, and it layers a recommender on top so a shopper answers a couple of questions instead of reading a table. Free plan, then $6.99/month.

Where it stops: a recommender is only as good as the measurements you feed it, and footwear brands are notoriously inconsistent between lasts. Garbage in, confident garbage out. Budget an afternoon for real measurements before you switch it on. Our guide to putting a size chart on the Shopify product page covers the manual version if you would rather not pay for anything yet.

MP Size Chart and Size Guide: 5.0 stars, 817 reviews

The rule-based alternative. You define which chart shows on which collection or tag, and it applies automatically as the catalogue grows, which matters when you carry twenty brands that all size differently. It is free to install and the first paid tier is $6.95/month, a few pence under Kiwi.

Where it stops: charts, not recommendations. If you want a shopper to be told “you are a 43 in this brand” rather than shown a grid and left to work it out, Kiwi or a quiz app does more. For a multi-brand shoe retailer where every label needs its own table, this is the more sensible shape.

Return Prime: 4.8 stars, 719 reviews

Here is the opinion that gets us disagreed with: for a shoe store, the returns app is a merchandising app. A footwear return is usually not a rejection of the product, it is a request for a different size of the same product, and if your returns flow offers an exchange before it offers a refund you keep the revenue. Return Prime runs that flow, free to install, paid from $19.99/month.

Where it stops: it works after the mistake. Every pound you spend here is a pound you did not have to spend if the sizing guidance had been right the first time. Buy the sizing app first. Buy this second.

Rubik Variant Images (ours): 5.0 stars, 410 reviews

Ours, so weigh it accordingly. It attaches a full set of photographs to each colourway rather than the single featured image Shopify allows, and filters the product gallery when the shopper picks one, hiding everything that belongs to the other colours. It handles multi-option products, which is the part footwear needs: images key off colour while size and width carry no photos of their own, so you are not asked to upload a picture of a size 44 in E width. Swatches come with it, on the product page and on collection cards. Metafield-based, no external API calls, native on 350+ themes including Dawn and Horizon.

“This is by far the best variant app I have tried, I deleted maybe 7 others after a slew of issues. Wonderful support as well!”

Anonymous merchant, 2026-02-06, Rubik Variant Images reviews on the Shopify App Store

Where it is the wrong pick, said plainly: 410 reviews against Loox’s 8,800 and STOQ’s 3,424 means we are the newer, smaller option, and if longevity is your filter we lose that comparison. It also does nothing whatsoever about sizing, which is the bigger footwear problem, so it should not be your first install. And if you list each colourway as a separate product rather than as variants, you want Rubik Combined Listings, which groups separate products into one listing instead. Free plan covers one product, Starter is $25/month for 100. Try it on the live demo store or read the getting started docs first.

The three smaller sizing apps, and who they suit

• Smart Size Chart and Fit Finder, 5.0 (130), free plan then $9/month. Charts and a fit finder in one, Built for Shopify, with a cheaper top tier ($19) than Kiwi’s ($24.49). Short track record, so treat the rating as promising rather than proven.
• Jotly Size Chart and Size Guide, 5.0 (62), free plan then $6.99/month. The only one here with a dedicated analytics tier, so you can see which charts get opened. 62 reviews is a fraction of Kiwi’s 1,085, which is the honest reason to think twice.
• Fit Quiz Size Recommender, 4.4 (34), from $35/month. A quiz that asks about height, weight and fit preference rather than showing a table. It carries the lowest rating and the highest entry price on this page, no free plan and no Built for Shopify badge. We wrote a full Fit Quiz review, including the usage pricing, because that model catches people out.

How to choose, in one rule

Look at your last fifty returns and read the reason codes. That is your buying order, and it beats any list including this one.

• Mostly “too small” or “too big”: a sizing app. Kiwi if you want recommendations, MP Size Chart if you carry many brands, Smart Size Chart if you want the lower ceiling price.
• Mostly “not as pictured” or “wrong colour”: a gallery problem, and that is Rubik Variant Images.
• Mostly “changed my mind”: not a product problem. Photo reviews from Loox give the next shopper more to go on.
• Few returns, but sessions ending on sold-out sizes: STOQ.
• Plenty of returns you would happily have swapped: Return Prime.

One more piece of unglamorous advice. Before you install anything, get the catalogue itself in order: consistent size and width codes, sane SKUs, image filenames that say what they show. Our free SKU generator will build you a scheme that survives a size run, and the image filename generator does the same for photography. Neither costs anything, and both make every app on this page work better.

Frequently asked questions

Which app should I use to show a different photo set for each shoe colourway?

Rubik Variant Images, which assigns a separate image set to every colourway and filters the product gallery when a shopper selects one, while leaving size and width without images of their own. It sits at 5.0 stars across 410 reviews, is free to install for one product, and runs natively on 350+ themes. If each colourway is a separate product, use Rubik Combined Listings instead.

How do I sell shoes in multiple widths on Shopify?

Width becomes a third option alongside colour and size, which uses up Shopify’s three-option allowance completely. It works, but the variant count multiplies fast: eight colours by twelve sizes by three widths is 288 variants for one shoe. Run your own numbers through a variant calculator before you commit to that structure.

Do size chart apps actually reduce returns?

They reduce size-related returns when the underlying measurements are accurate, and do nothing at all when they are not. A chart copied from a supplier PDF that does not match the shoe you received will make things worse, because shoppers trust it. Measure a pair from each last yourself.

Should colourways be variants or separate products?

Variants keep one URL and concentrate reviews and ranking signals on it. Separate products give each colourway its own URL and its own chance to rank, at the cost of a collection page that shows the same shoe six times. Both work. They just need different apps, which is the honest reason we build two.

How many apps does a shoe store need?

Three is usually right: sizing, gallery, and one of reviews or restock alerts depending on whether your problem is trust or stock. Every extra app is a monthly fee and page weight forever, so add them one at a time and measure in between.

Are any of these free?

Kiwi, Smart Size Chart, Jotly, STOQ, Loox and Rubik Variant Images all list a free tier with limits. MP Size Chart and Return Prime are free to install with paid upgrades. Fit Quiz is the exception on this page with no free plan, starting at $35/month.
