great option for a taller running sock
i needed to find a taller pair of socks for trail runnign to keep the dirt out of the back of my shoe/heel. these work great, enough padding, but not too thick, crazy design to keep it from being borig. i got these for a great price from REI outlet and will definitely order another design if i find it.
