These (socks) were the best equipment investment that I have made for track and field officiating this year. After some long days while officiating track and field meets, I have never had a season where my legs felt this good after a meet. In fact, for one meet, I was on my feet from 9 am to 7 pm. Yes, I was tired and sore, but when I got home, I did not have swollen and discolored feet and ankles from pooling of fluids from a long day on my feet. The SmoothToe socks are great!
