Not sure which size? Measure your foot below — it takes two minutes.

Sizes on this product are EU whole sizes. Your most reliable reference is your foot length — measure it below.

8.8 in	4	5.5	36	3

All sizes are EU whole sizes — no half sizes. *US conversions are approximate: a whole EU size often falls between two US sizes. If your US size or foot length lands between two rows, choose the larger EU size.

How to measure your foot

Place a sheet of paper on the floor against a wall. Stand on it barefoot, heel touching the wall.
Mark the tip of your longest toe on the paper with a pencil.
Measure the distance from the edge of the paper (wall side) to your mark.
Compare your measurement with the Foot length column above and read your size across.

Tip: measure at the end of the day — feet swell slightly — and use your larger foot.

Trail-ready cushioning and grip. A rugged Vibram Megagrip outsole and plush Fresh Foam X midsole handle technical terrain in comfort, run after run.

Built for broken ground and bad weather — grip, protection and a lockdown that holds on a descent. New Balance is the brand people buy when they stop caring what's trending and start caring what their feet feel like at 6pm.
