Perfect for running and playing tennis
March 10, 2013

This is my first time to wear Smartwool socks for tennis and I was skeptical about it but surprisingly, it fits right and stayed well despite of the running, turning and sliding on the court. The other socks I've used had this concern so from now on I will stick to smart wool and buy more, for sure. Thank you Altrec!

Pros: Great design, Build quality, Lasts forever, Performance, Ease of use, Cons: Cost, might be too thin for some tennis players.

A Treat for your Feet
September 10, 2013

Love these socks. Although they are a bit pricey, they are worth every cent. i wear them for work in public safety where I am on my feet most of the day. They breathe great, do not absorb sweat, and are lasting well. Don't wait to grab this deal.

Pros: Great design, Build quality, Performance, Cons: Cost
