This is the first time I've tried Crocs. I wanted something I could wear in the yard and just hose off if they got muddy. These are fine for that and even have a minimal footbed insert. As for wearing them all day- that's not something I can imagine. Plastic doesn't breathe and they would be far too rigid for me. They run a lttle large, and I usually wear a 10 1/2 with heavy socks so the 11 is too big. That's always tough to guage with a shoe brand you haven't worn before. Basic inexpensive shoe for puttering around outside or in. But all day? No way.
