Have had several pairs of Grisport boots before with no real problems. I purchased a pair Thunder Trecking boots in Oct 2019 and due to Covid lockdown only really started wearing them on a regular basis from about April. The soles have really worn down and I now have put in gel insoles but still can feel small stones etc . They have also recently started come apart where the sole meets the leather upper. My main gripe is the company when contacted to discuss the matter never responds back. These boots did not have Vibram soles as my previous ones did. I gave 5stars when I first purchased them but can only give one star on my latest dealings. The company advertises them giving Years of Wear. On this pair I will be lucky to get 12 months. Very disappointed with boots and sevice
