I think these Crocs will last forever; maybe because I won't wear them very often. They're not flexible because they're not squishy Crocs material. With regular Crocs, my narrow/medium width feet sink in and the shoe conforms to my foot. With these and their much firmer base, I don't sink in and they're really too wide. I'll wear them in the Winter with thick socks, otherwise, I'll walk right out of them. I'd suggest a more flexible sole, or a narrower base.
