So I want to start by saying they are wonderful and very comfortable right out of the box. BUTTTT.........Sadly the insoles in these failed and tore after just 4 months of moderate use. I approached the company about the issue and replacement for new soles.  Unfortunately the company does not offer replacement under warranty nor to purchase. I was directed by the company to purchase Ortholite Fusions and to quote them "which delivers equal comfort and stability" which is far fetch and not accurate at best they alter the comfort of the shoes completely due to there design not being similar. I give Salomon Speedcross 4s 2 stars because the shoes are comfortable and very functional on the trails but the insoles don't last and they don't stand behind there products to well. Salomon should take care of there customers better.
