Saucony are almost back to their normal size. I have 11.5 on Asics, 11 on Merrell and now 11.5 on Saucony (previously 12 and before that 11). I love the Everun outsole! It's so comfy and soft for my 210 lb dad body with back knees. They used a mesh upper that conforms well to the foot and is breathable. Rolling is not necessary. The tread pattern is only fairly aggressive on the Xodus and Koa ST. This shoe is lighter than both. Good for trail running and OCR, although for the latter I still prefer Xodus and KOA ST.Fyi, no rock slab.
