Ruslan Kadyrov 5 I always had problems with sneakers - even after not long time of usage inner backs of sneakers were totally destroyed. So decided to check current product.To be honest, no disadvantages were found for 6 months of usage.Not slippery, comfortable, and finally backs of sneakers are protected! Second pic is current product after 6 months of intense usage.Definitely recommend if you want your favorite sneakers live long!
