I love these shoes! I previously had the Nike Free Runs and I bought these to slowly train in and just try out the most barefoot running shoes. I thought I'd take forever to be able to run in these and perhaps they'd just become daily shoes. They were so comfortable! I started training in them after an injury and it didn't take long! I feel like I don't ever want to run in anything else I have not experience knee pain like my previous shoes! I went to order a second pair and was disappointed at the lack of color selection. Will you be getting more colors out again?
