I received my VFF KSOs ... last Friday. I thought they were too small. My pinkie toe wasn't happy being separated from my other toes. I have been wearing them every other day, and the last time I wore them (Monday), I consciously relaxed my feet, and... wha la, they fit My pinkie toe didn't have a problem. I was able to run and jump and play in them... it was fun. The next day I noticed the muscles in my lower calves were a bit sore - probably because I have been running in big wedge running shoes forever... but I'm taking it slowly and it's going well. The dogs have fun chasing me around grassy fields for now too...
