Love this brand, Im super hard on shoes and can usually get 6 months out of them before they need to be replaced. These ones lost several pieces of rubber off the bottom of both shoes as early as 3 months in. Still feel great but not as durable as others Ive had from this brand. In comparison I can get 3 months out of Asics and 2 months out of most other brands of running shoes which is why I stick with this brand
