“I used these one time so far, for my very first Tri - a Sprint but used them for the bike and run portion. My feet felt great the entire time. No issue at all with sweating, sliding, being ripped, etc. These things are incredible. I have a pair of Aspire 12 but will be using them strictly for OCR races. These are exclusively my Triathlon socks. Ordering a backup pair just to have. I'm a fan!”
