Comfy, great quality
Size: 6-10, Color: White
I’ve had these for quite a while now. They are holding up very well as i wear them a lot for work (coaching). They are very cushiony and most importantly, they do not slip! I would compare these to Bombas but at a significantly better price point.

My favorite socks now!
Size: Medium, Color: Deep Sea/Breaker Blue/Electro Pink
I love socks! And these are quickly becoming my favorites! They do not slide down into your shoe no matter if you are working out or just wearing them for normal everyday use. The price is a little higher than I would normally pay for 3 pair of socks, but after wearing these for a few weeks, I think the quality and comfortability of these socks is well worth the money.

Quality, comfort and support.
Size: Medium, Color: Deep Sea/Breaker Blue/Electro Pink
These socks are the bomb! If you are athletic or on your feet for extended periods these great looking, well made socks are constructed to offer just the right amount of compression and support. The toe is soft and thick. I will order these again and again. Hopefully Amazon will add even more color choices on the future.
