I’ve been a Swiftwick fan for a long time but seeing these tie dye dudes had me wanting to branch out. So I did, and soooo glad I did. These socks are highly comparable if not a bit better than swiftwick socks so I ended up 🤙🏼

I bought my husband these socks in 2015 when he ran his first marathon. My husband still 7 years later wears the same pair of socks. The pair I just purchased are for my son who will participate in his first triathlon.

I'm a size 11.5 shoe and got a large. It fits great! Wore them for a run already and had not issues.

These socks are awesome. Fit well, not too warm, not too cold, and they take the abuse of the washing machine well. I wear them everywhere

Why Runners Make The Switch
01. Sorbtek® Moisture Wicking
Proprietary fiber technology pulls moisture from the foot to keep you dry and reduce hot spots -- the #1 cause of blisters
02. Targeted Compression Zones
Support where it counts: arch, ankle, and Achilles. Reduces fatigue so you can go harder for longer.
03. Reinforced Impact Areas
Extra cushioning in the heel and ball of the foot -- the zones that take the most punishment on pavement and trail.
04. Lifetime Guarantee
If they wear out, develop a hole, or arrive defective, we'll replace them. No questions. No hoops. No expiration date.
