First ruck (5k) with these felt great! Cant wait to try them on longer distances.

Daryl Booi
Best yet!

I've worn Wright socks for just over a year and have never been dissappoiinyed.
I bought one pair of the double marino, what a great sock!
My only issue is I should have bought several pairs!

James Couch
Great Winter Socks

Tried these out the first really cold day (temps in the teens) and they kept my toes nice and toasty. Much better than using two pairs of socks, which I had been doing. Well worth the cost.

Jack Maarcus

The socks are soft and protect my feet
