I live in fitflops... The clogs, the sandals, and the slippers! So I absolutely love them. But some Styles run too big and some run too small. Historically my slippers have stretched out more than I like. But these are staying very snug. I bought my true size, an 8, and these are staying true to size. Don't expect them to stretch out if you're used to other models of FitFlop slippers that stretch out a lot.
