Brand-Specific Sizing Notes
Nike
Nike running shoes generally run true to size. However, Nike Free and Flyknit styles tend to run half a size small due to their flexible construction. Nike football boots often run narrow — consider going half a size up if you have wide feet.
Adidas
Adidas trainers typically run true to size in UK and EU sizing. The Ultraboost and NMD ranges run slightly long. Adidas uses EU sizing as its primary standard, so always cross-reference with the EU column above.
New Balance
New Balance is known for offering the widest range of width fittings — from AA (narrow) to EEEE (extra wide). Their running shoes tend to run true to size. Check the width code on the box when ordering online.
ASICS
ASICS running shoes generally run true to size or slightly long. The Gel-Kayano and Gel-Nimbus ranges are popular for wider feet. ASICS uses Japanese CM sizing internally, which aligns closely with foot length measurements.
Brooks
Brooks running shoes are designed for performance fit and typically run true to size. The Ghost and Adrenaline GTS series are available in multiple widths. Brooks recommends measuring both feet and sizing to the larger foot.
Puma
Puma trainers can run slightly small, particularly in lifestyle and retro styles. For running and training shoes, Puma generally aligns with standard UK/EU sizing. Football boots from Puma tend to run narrow.
Athletic Shoe Fitting Tips
Running Shoes
- Allow 1–1.5cm of space between your longest toe and the shoe end
- Feet swell during runs — size up half a size if you run long distances
- Try shoes on in the afternoon when feet are at their largest
- Wear your running socks when trying on shoes
Football Boots
- Football boots should fit snugly with minimal toe room
- Leather boots will stretch slightly with wear — size true
- Synthetic boots do not stretch — size up half a size if between sizes
- Consider the playing surface: firm ground boots fit differently to astroturf
Basketball Trainers
- Basketball shoes should feel snug but not tight around the midfoot
- High-top styles provide ankle support — ensure the collar does not rub
- Allow a thumb's width of space at the toe
- Many players size up half a size for comfort during long games
