I still wish I could get another pair of Clarke Springers. But they aren't cheap. But GOSH I love 'em! I swear...they gotta be elf made. They're so light and comfortable, and wearing them is almost just like going barefoot without having to worry about getting hurt on rocks and such.
These sandals are made out of this ultra soft foam rubber and surgical tubing.
You don't break 'em in. They break you in. You're feet just get used to them. So they are a bit hard to get used to. But after you do, they are very comfy.
