For me these are not the most comfortable altras due to the waterproof liner. The lining seam runs all the way back at the heel, which can be annoying with thin socks (I wore Darn Tough socks and couldn't see the seam). I am very happy with them. By the way, I've been wearing Altras for many years and I'm ALWAYS satisfied with the durability. People seem intent on forcing Altra to scale up their shoes until they're as uncomfortable as other brands.
