First pair, and did take a bit to get on, but my toes aren't spread-out like that :). The first day I wore them for 5 hours, and at the end my heel was getting a bit sore. I will wear them only a few hours day when I exercise, but I will be buying more for sure. They are like being barefoot. The only negative I have is when walking on gravel (I have to in my small town) you can feel a rock if you step on it just right. It hurts a bit.
