The wife struggles with socks. She only like the Nike ones, then they discontinued them, so had to start the search again! Found these, they are expensive just like the Nike, but the size is true, they look great, they are super soft and stretchy. They are light weight and breathable and seem to wick away moisture. She loves these!

I wear a women’s size 9.5 and I got a size Medium. They fit perfect, they aren’t super heavy, but have cushion where needed. Perfect for my steel toe boots

Quality and durable socks

Great quality socks. This pack was a lot taller on the cuff and bigger than previous batches I have had. Not sure what the change was, but giving it 4 instead of 5 because I preferred the smaller shorter ones they previously made. But these are great quality socks, and last a long time.
