These might be the perfect summer sock I've been searching f
Let me tell you my sad sock tale. About 35 years ago I decided I would only buy one type of sock, same sock, same colour. My sock of choice was the regular Smartwool hiking sock. I've likely had 50+ pairs, and when I get a hole in one, I just chuck it out and pair the widow with another sock as they...

Sigh. Another "new" product worse than the old one.
Been buying the Phd light hikers for at least 10 years. Love them. Best socks ever. Wear them EVERY DAY unless I have to dress up fancy, am backpacking heavy, or I'll be outside for a while when it's below freezing. Only problem is they tear around the ankle after 1-2 years from the tension of pulli...

Very comfortable socks
Very comfortable socks. Second Cut allowed me to second purpose all of my old socks.
Perfect, again.

Been wearing Smartwool socks for a long time
They last for a long time and are comfortable. I hope my new ones last as long as my old ones.
My New Running Fave Socks
I use them to run in with the added cushion. Need more of these in the running category.
Great socks!
These socks are warm, and cushy. Love them for hiking or just to wear in the winter.
My husband Loves these socks!!
These are my husband's favorites, bc perfect amount of cushion, breathable and wash up well also!! ❤️
Perfect height, cushion and fit. LOVE the colors too.
My go-to for socks, for years. I love the mid-crew and crew length for all types of boots, but if you want a "no-show" similar sock for boots, these are IT. Great for other hiker shoes as well. The cushion is just the right amount to not feel super thick, but aids where there is the most pressure when on your feet for long periods of time. These also help prevent chafing from new footwear and/or prolonged wear.
Excellent and enduring socks
Smartwool makes excellent socks. I bought a bunch of them about ten years ago and only now, just replaced them all.
I would recommend these socks!
As an outdoor enthusiast it is important that the cloths I wear are durable and can stand the rigors of my adventures. The high ankle socks are my go to for hikes and back packing trips. They keep my feet dry and warm which is key to reduce hot spots on my feet.
