I find that the few times I have worn my Trail runners which are 1 size larger then I normally would wear, I got some serious toe bang and my toe nails got black n blue and eventually fell off. Never had this problem when I wear the exact size I normally wear. The reason I was wearing one size up, was for cold weather when I would wear a thin baselayer sock and then a heavier sock over it.. But these 2 trips I just wore a lightweight sock ..so my foot apparently was sliding a bit and on the descents my toes were smashing front end of shoe!
Just ranting a bit here.. I always hear people say to go one size up.. I don’t get it! My piggies were hurting from this.. Like never before.
