I was so excited to try these because I am in love with their go walk shoes.  I wear them to work every day.  I am a runner and wanted to check out these.  Unfortunately I ran one mile in them and by the end by ankles were feeling like they were getting sprained.  I still have a little bit of discomfort the next day from wearing them.  I loved how light they were though.  I guess I have to stick to the go walk line for now.
