Honestly, I'm pretty disappointed in them. I was hoping to wear them to an amusement park instead of tennis shoes, but I really don't think that they will work for me. I usually wear a 9/10 in the $1.00 flip flops from walmart, and they tend to run pretty big for me. I have lots of flipping room....I ordered a 10 in these to give myself lots of room...well thank goodness. My feet take up the ENTIRE thing. There is NO extra room either at the toes or the heel. I am pretty product loyal, and for being Nike, I am pretty disappointed in them.
