I had ordered black socks and I received white socks. What’s up?

CHAD C.

Love these socks! I just keep ordering more and more! No matter how long of a run I do or how hard of a CrossFit WOD I do, my shoes are not wet and nor are my socks! RLTW DOL GRS

Darren D.

Good fit and feel . I wear to Boot Camp work out every day

Robert F.

Very thin and comfortable sock. Fit is way off. I’m a size 8 and the other large fitsoks are a perfect fit. These barely get up to my ankle and are snug

Diana S.

I have worn these socks forever. I want more of them. They fit and don't scrunch up when I put my shoes on. I have foot trouble and they are PERFECT! I am an actress, if you ever want to advertise on TV please call me!!!!! I have the spring, summer and winter ones in quantity.

Frederick C.

You got it right with these socks. Just the right thickness, perfect fit, and on sale!

John S.

I bought these because Fitsok was out of the CF-2 socks in the large size that I originally wanted. I should have waited until the CF-2’s came back into stock, I like them better.

Cheryl L.

Great fit , great socks

Cameron H.

I really like the feel and "weight" of the sock. I have many pairs of FitSoks and have been looking for a lighter weight than my usual wool blend. The only thing I notice on first wearing is that it slid slightly in my shoe when running, but I think that may resolve itself after a few washings.

Peter A.

Fit great. Very comfortable. Feel high quality.

Janice V.

Thin, comfortable, move with you and allow you feet to breath.

James O.

I purchased 4 pair of low cuff socks for my work, and I absolutely love this item, quality and comfort. I will purchase more and refer anyone who is on their feet alot to buy these.

cory s.

Good fit comfort

Gail L.

I needed some supportive, thin socks for trail running. I have a 50 miler in a couple of weeks. Tried these socks out on a 26 mile training run and they were perfect. No hot spots, no blisters. I'll be taking these with me. And, from previous experience with Fitsok, these things last!!

Gordon R.

Great for running. Good cushion, a little thinner and better wicking for hot days

Tyler S.

My son loves them

Marci B.

They are nice and thin but not flimsy. I wish they were a smoother fabric but they aren’t scruffy. Very form fitted so not loose or saggy. Tailored well.
