I'm so glad he is pain free for that time. That is wonderful. It will be interesting to see in more time if it works or it was just a fluke. I hope it works. Maybe his toes were rubbing together and the cotton helps keep them apart. The doc probably didn't think of something outside the box like that other then a med or procedure. Sometimes little adjustments can make a huge difference. I know even a different material can send my pain in different directions. I'm sure he will be happy without his boot. I can remeber how annoying mine was but the transition was hard to the shoe. I'm glad things are looking better for him. Hopefully you guys will be dancing soon together.
