Package came ripped up, doesn’t make me feel good about wearing them.
Great socks! Cushy!!
I’ve found the anti-blister socks to be an answer to a prayer as I’d been having problems with blisters and calluses until I remembered having an old pair of the socks. I googled the company and found it to be still a thriving business so I ordered a few pair of the socks. My order arrived in record time and when I discovered a problem with one of the socks, I contacted customer service and they responded and sent out a new pair the very same day. In this day and age, I’d come to forget what great customer service is like!
Excellent socks. However, the XL is a little small. I wear a size 12 shoe and your XL is barely large enough. Size Matters.
I’ve been wearing Wrightsocks for over ten years. I don’t think I’ve ever gotten a blister!
