These are the most comfortable flats I've ever owned. It feels like I'm wearing socks that won't slide off my heel.

If they're slightly too big or too small for you, you can stretch or shrink the material with heat. Slight heat. Either tumbled on low heat in the dryer or with a hair dryer.

I've noticed many reviews that had me hesitate to buy these. And indeed I bought shoes in the wrong size at first. Too big. But I returned them at no cost to me and bought a smaller size. Perfect.

Don't knock them 'til you try them. And if they're too small or too big, try the next size up or down to see which one is a closer fit.
