I worked out in these. These sweaty, smelly socks I worked out in have been steeping for days, especially for you - am I not so generous? They need a good wash... Open wide, stuff them inside your mouth, let your saliva build-up, melt away all the crusty grime, all the sweat. The brown spots on the sole and on the heel will need particular attention though. I want these socks spotless when you're done! x
