GUC worn for one rail-trail marathon (packed dirt) and a handful of training runs so there some light tread wear and scuffing. Just a bit too big/wide for my preference. Under 60mi total though and I can usually run in adidas shoes for 400+ miles! Really bouncy, fun and forgiving, perfect for long runs and races. Best on smooth surfaces. Spacious toebox height and width. Sizing is unisex. These are M6/W7.5 and fit like a spacious 7.5. For reference: I am generally W7.5 in Saucony/nike/new balance but W7 in adidas/Hoka.
