Since its launch in 2018, London-based sneaker label Uniform Standard has been going from strength to strength, building up a loyal base of fans. Aside from the label's sleek, minimalist aesthetic that extends across its full range of leather sneakers, what has really captured the attention of premium sneaker lovers is Uniform Standard's focus on sustainability. This focus is becoming — for good reason — increasingly demanded of fashion brands the world over and Uniform Standard has been a shining exemplar, championing ethical production and responsible sourcing of sustainable materials. Sustainability permeates all steps in the production and retail process, and we often ignore the environmental impact of shipping items back and forth. With this in mind, we’ve laid out a simple guide to Uniform Standard sizing, so that you needn’t buy a pair of sneakers to try before having to return them due to an incorrect fit. 

Uniform Standard size guide

We’ve dealt with some tricky size guides in the past, where each style comes with a page of warnings and confusing stipulations. Luckily, this is not one of those. Every Uniform Standard sneaker fits true to size. This means that you don’t need to make any calculations to ensure that you get the ideal fit. Go for your usual size. This said, the label doesn’t deal in half sizes. If you usually wear a half size, we recommend that you size up. 

The chart below will help you make the conversion between UK, US and EU sizes.

Uniform Standard fit guide

While Uniform Standard sizing may be easy to understand, each Uniform Standard style fits slightly differently, so it’s worth assessing which style might be the best fit for you. 

Series 1 fit guide

The first of the label’s offerings, Series 1 is a super minimalist, handcrafted men’s shoe made from fine Italian leather and a low-profile, recycled cupsole. There are no surprises with this style, and that’s why we love it so much. The timeless shape means that it has a medium width in terms of fit, so this is a safe bet if you’re unsure on whether you prefer a narrow or wide-fitting shoe.

Series 3 fit guide

Uniform Standard Series 3 is inspired by the iconic design of a mid-century German army trainer. This sleek and sporty style is made up of a recycled low cupsole unit, soft textured leather uppers and a contrasting suede toe apron and heel counters. This lightweight style has a more narrow fit to give it its streamlined characteristic.

Series 6 fit guide

Series 6 finds its roots in basketball footwear. Taking design cues from the classic u-shape basketball profile, Uniform Standard’s Series 6 is made by hand from premium Italian smooth calf leather uppers and features a fully recycled footbed and insole board. The design affords a little more room thanks to its basketball origins, so this is the widest style in the collection.

Series 8 fit guide

While Uniform Standard’s Series 8 is a similar style to Series 1, a new recycled rubber wedge outsole lends the design a contemporary twist. A host of recycled elements make up Series 8, such as the 70% recycled wedge cupsole, 100% recycled footbed, 100% recycled cellulose insole and 100% recycled shoebox. When it comes to fit, Series 8 has a regular width, much like Series 1.
