I have purchased other brands of these type of nylon ankle socks and been very disappointed in how quickly they would get runs in them. I could only wear them a couple of times before seeing runs. However, this brand is amazing. I have a pair that I have worn over and over and over many times and still no runs! Ok, now maybe I am seeing the start of a little run after wearing them all day several times. I really feel like I got my money's worth purchasing these. I love them!
