The Cogs are OK for the price, especially I think it's great that you have a feed, which is also removable and washable. This is very handy. I bought them for the winter, cause I bruachte tabile slippers for winter. Shoes are light and soft, comfortable on foot, feed itself does not take off.
2 points deduction because: - Lining made of pure plastic, feet sweat even in winter - If you rausnimmt lining, the shoe is equal to greater than 2 to almost number - does not fit well. Since it has not yet become the summer not bother me so today ......
