Reviews:

I am very happy with the product even though I think it has changed slightly along the years. I still have some of the first ones while this new generation is more prone to holes. Don’t ask me how I know it… Also I would love if you could some how ‘mark’ each batch of the sockscription with a small different Mark so that I can pair them properly across the years. For instance: December is blue, spring is orange, summer green. It could also be the thread in the toe tip… but it would greatly help. Especially because I share them with my son.

Some of the seams are coming loose after a very short time, not worth the money , I thought they were good, but disappointed after a few weeks.
