I bought these socks as a Christmas present for my boyfriend, who’s a size 13 and often struggles to find comfortable socks. Not only are these incredibly comfy, but they’re also perfect for his marathons! He’s now completely hooked and only wears Sums. The quality, fit, and comfort are unmatched. Please bring out more colors and designs; we can’t wait to add more to his collection! Highly recommend to anyone looking for the perfect blend of comfort and performance!
