These are my favorite Sanuks. I've tried on many and none are as soft as this. They're flattering on my flat feet. There's no break in time and I can wear them for hours and hours. If you're half size, go up to the next one and it'll fit perfect. I wore my last ones out and I thought I'd give the Springwaters a go, but they didn't cut it and now I've come back to the good old reliable yoga mat flip flops I love.
