I have used these for working out and walking for a couple weeks now. I love them. At first, I thought oh no these are too tight. But after I wore them for an hour or two to break them in, they were fine. I wear a size 7 and I bought a size 7. They are light weight and feel great not having heavier shoes on. I actually came back to buy another pair in another color and they were over $20 more than I originally paid. I picked them up for $39.95 and I will wait until they go back down and get another pair.
