I usually wear ankle socks when playing tennis, but the other athletic socks I own kept bunching up in the sneaker. For whatever reason, these socks (which are quite thick and provide a bit of padding to the insole) stayed up just fine. So, on top of being provided with a bit more shock absorption, I also don't have to worry about having to take my sneakers off to pull up my socks. The price per pair was also very inexpensive, especially given the high quality of the socks. A worthwhile purchase.
