My husband and I are both LBKA. We’ve tried antiperspirants and other liner socks to deal with sweat issues arising from leading an active lifestyle. Nothing really seemed to help much until I heard of the Valor sock and ordered a pair to try them out. Wow, what a game changer. They allow us to work all day and do moderate exercise without having to remove, wipe down and re-apply our suspension systems. They are easy to size, comfortable to wear and easy to maintain. I highly recommend them. I have shown them to my prosthetist and he has now ordered them for other patients. Thanks for a great product.
