- 8 1/2
- shoes size
I have a few Matrixx sneakers and they are very comfy. I usually wear USA size 8 or 9 (Nike shoes in size 8, Metcon shoes size 8.5) For the Matrix, if you are usually a size 8 or 8 1/2, you should consider sizing up to a size 9. I have size 8 and 9 and I preffer the 9. The size 8 are a little too tight. Both fits but the size 9 is better.
