I bought M size equivalent for the color, and room for long distance trails when feet expand and splay in heat. I have high arches and I feel the under support. I wish they were a higher drop but the slight forward rocker helps. They have good grip on mixed dry terrain and support when I run downhill. Once you get your lock down they’ll be good. I have wide feet, one foot is defined wide yet other is longer. I search for W trail shoes with 8 ml drop and cushion for ultra trails … is there a perfect shoe?? I have 2x 10 mile runs in this and hope they’ll feel even better with miles done. They look good and are a good color for trails and nicer than the Women’s right now. I do have some nerve irritation in one foot must be the underfoot support, it’s not pain but a feeling that goes away next day. I got gaitors on Amazon which still work without sticking them down on rear of shoe. I have 2 pairs of the evo SL, but don’t think that these are the trail version as they fit and feel differently.
