Getting replica sneaker sizing right is the single most important step before you place an order — and it's not as simple as ordering your usual US size. Because our 1:1 replicas are manufactured to the original spec using the same lasts and materials as the originals, the sizing often mirrors retail, but there are batch-specific quirks, model-level nuances, and conversion gaps worth knowing about before you commit. This guide covers everything: conversion charts, fit tendencies by silhouette, half-size strategies, and red flags to watch for.
Why Replica Sneaker Sizing Feels Different
High-quality UA replicas are built on the same construction blueprints as their retail counterparts, which means a well-made replica Jordan 1 should fit exactly like the shoe you tried on at Foot Locker. The key phrase there is "well-made." Lower-tier batches use cheaper foam compounds that compress faster or molds that haven't been properly calibrated, leading to toe-box squeeze or heel slippage. At UADEPOT, we source only from established batch suppliers with verified lasts — you can read more about how we vet each drop on our quality assurance page.
That said, even mirror-grade replicas can feel slightly off if you don't account for the model's known sizing personality. A Yeezy Foam Runner fits completely differently from a Nike Air Max 97, and treating them the same will cost you a return.
US, EU, UK & CM Size Conversion Chart
Most of our suppliers label boxes in both US and EU sizes, but centimeter (CM/insole length) measurements are the most reliable reference point when you're unsure. Here's a quick cross-reference for men's sizing — women should subtract 1.5 US sizes from the men's column:
- US 7 / EU 40 / UK 6 / 25 cm
- US 8 / EU 41 / UK 7 / 26 cm
- US 9 / EU 42.5 / UK 8 / 27 cm
- US 10 / EU 44 / UK 9 / 28 cm
- US 11 / EU 45 / UK 10 / 29 cm
- US 12 / EU 46 / UK 11 / 30 cm
- US 13 / EU 47.5 / UK 12 / 31 cm
When in doubt, measure your foot from heel to longest toe while standing, add 0.5–1 cm for movement room, and match that number to the CM column. This sidesteps any brand-to-brand conversion ambiguity entirely.
Fit Notes by Silhouette
Nike & Jordan Silhouettes
Nike replicas generally run true to size, but the category is broad enough that you need to go model by model. Air Force 1s are famous for running wide and a half-size long — most rep buyers who wear a US 10 in Dunks comfortably size down to 9.5 in AF1s. Jordan highs (1, 4, 11) run true with a standard medium width, while the Jordan 3 and 5 tend to run slightly narrow through the midfoot. If you have a wide foot, size up a half.
Adidas & Yeezy Silhouettes
Adidas replicas using Boost midsoles (Ultraboost, NMD) run true to size and often feel slightly roomier than Nike equivalents at the same number. Yeezy sizing is the most discussed topic in the replica community: the 350 V2 runs a half-size small for most people, the 500 runs true, and the Foam Runner fits large — most buyers go a full size down on the Foam Runner.
New Balance, ASICS & Running Silhouettes
New Balance 550s and 990s run true to size with a generous toe box — great for wide feet. ASICS Gel-Kayano and Gel-NYC replicas also run true but have a noticeably narrower last than New Balance, so wide-footers should size up. Salomon XT-6 and Speedcross reps run a half-size small; Salomon officially recommends sizing up and the same logic applies here.
Half Sizes: When to Go Up, When to Go Down
Not every model is produced in half sizes by every batch supplier. When your ideal size isn't available, the rule of thumb is: go up, not down. Shoes can be managed with thicker socks or an insole insert if slightly large, but a shoe that's too small will simply be unwearable and cause blisters. The exception is wide-toe-box silhouettes like the Air Force 1 or New Balance 550, where going up a half size can cause heel slippage — in those cases, half an insole pad at the heel solves the problem cleanly.
Batch Quality & How It Affects Fit
In the replica world, "batch" refers to the specific factory run a pair comes from. Different batches of the same model can vary slightly in insole thickness and upper material stiffness, both of which affect perceived fit. Premium batches — the ones we carry — use the same EVA compounds and PU foams specified in the original's technical sheet, which means the break-in period and final fit mirror retail closely. Cheaper batches cut foam density, so the shoe feels stiffer at first but compresses dramatically after a few wears, going from snug to sloppy.
When you're comparing batch options, look for these quality markers:
- Insole stitching that lies flat with no puckering at the toe or heel edge
- Midsole material that springs back when pressed — not foam that stays compressed
- Upper leather or mesh that matches the grain/weave pattern of retail samples in side-by-side photos
- Lace holes reinforced with metal eyelets on models that use them (e.g., Jordan 1, Air Force 1)
- Outsole rubber that is flexible at room temperature, not brittle
- Heel counter stiffness matching the silhouette — a soft heel on a Jordan 4 is a red flag
Women's Sizing in Men's Models
Many of our most popular silhouettes — Jordan 1 Low, Dunk Low, Yeezy 350 V2 — are produced primarily in men's sizing by batch suppliers. Women shopping these styles should convert by subtracting 1.5 from their US women's size (so a women's US 8 = men's US 6.5). Width is the other consideration: men's lasts tend to run slightly wider through the ball of the foot, which many women find more comfortable in athletic silhouettes. For styles produced natively in women's sizing — like many UGG replicas or Converse Chuck Taylors — size charts are straight women's US and no conversion is needed.
Frequently Asked Questions
Do replica sneakers fit the same as the retail version?
In most cases, yes — especially when you buy from a reputable supplier using verified lasts and correct materials. Mirror-grade 1:1 replicas are built to the same dimensional specs as the originals, so a size 10 replica Dunk Low should fit like a size 10 retail Dunk Low. The exceptions are model-specific quirks (like the AF1 running long) that exist in retail too, and occasional batch inconsistencies in lower-quality runs. Sticking to established, well-reviewed batches minimizes those surprises.
What if I'm between sizes?
Always go up unless you're buying a silhouette known to run large (Air Force 1, Yeezy Foam Runner, Salomon XT-6). A half-size up can be corrected with a thin insole or slightly thicker sock; a half-size down leaves no room to adjust. If you're genuinely on the border — say, a size 9.5 in some brands and a 10 in others — use the CM measurement method: measure your foot, add 1 cm, and match that to the insole length listed in the product detail.
Can I return or exchange if the size is wrong?
We handle size issues on a case-by-case basis. Because our inventory ships directly from suppliers, exchanges take longer than a domestic return — typically 2–3 weeks for a replacement pair. That's exactly why we put so much effort into sizing guidance upfront. If you're genuinely uncertain, reach out before ordering and our team can pull the actual insole measurements from the specific batch in stock. Getting the size right the first time is always the faster path.
