The seam is so stiff! I bought for my son as the size of Bombass socks he wanted was out of stock so thought we'd give these a try. Once my son put them on you could feel the "hump" from the stitching and it's actually quite hard. To be honest I don't understand how they manage to call them seamless when they obviously aren't. I've bought Jefferies sport socks before and I think because the bottom part is thicker you can't feel or see the seam, but they are completely different and I won't buy…
