Best Trainers UK: Do Skechers and Asics Fit True to Size?

By Sahir, Founder of Soleistic

Quick answer: Skechers — our most-stocked trainer brand — generally fits true to UK size, with four width fits from a snug Standard (D) to Extra Wide (4E) per Skechers’ own guide. Asics recommends sizing up half a size for running-style trainers, since feet swell during exercise. Below are our current picks from Soleistic’s catalogue, with live UK pricing — try any of them on your own feet with our AI try-on before you buy.

Do Skechers trainers fit true to size?

Generally yes — Skechers’ own UK size guide describes four width fits, from a snug Standard (D) fit to Extra Wide (4E), so a size that feels tight in one style may need a wider fit rather than a bigger size. One exception, per Skechers themselves: Performance running, walking and golf styles can vary from standard sizing. See Skechers’ official size guide for the full breakdown.

Should I size up for Asics trainers?

Many UK retailers recommend sizing up half a size for Asics running-style trainers, since feet swell during exercise — Asics’ own guide also lists extended 2E and 4E wide-width options on styles like the Gel-Kayano and GT-2000. See Asics’ official size and fit guide for the details.

What’s the difference between a comfortable trainer and a running shoe?

Running shoes are built specifically to absorb repeated impact and support a running gait, while everyday trainers are built more generally for comfort and style — a good running shoe usually works fine for walking too, but the reverse isn’t always true.

Do these picks change over time?

Yes — this page pulls live stock and pricing from Soleistic’s catalogue each time it loads, so the picks and prices you see reflect what is actually available right now, not a fixed list from when this guide was written.
