Review on Bamboo Graduated Knee High Compression Socks - Enhances Circulation, Controls Swelling, Odor & Blister Protection by Fort Steffen

I bought these for my father who recently had a stroke. He's been wearing them every day for the past 3 months and so far has only put a hole in one of his socks. It wasn't the bad quality of the material, it was his toenails. Just wanted to mention this as I've seen some reviews say it's about holes. My brother who takes care of my father only washes lukewarm and doesn't dry them if that helps.
