Within 6 months the sole came apart - the laces came undone, they are very bad and cheap quality - they fall apart very quickly, the mesh tore, but the most unbelievable thing is the many and intense pains in the feet! I bought another company’s and within two weeks I am recovering in my feet, slowly but steadily. I couldn’t even climb stairs, I thought something had happened to me. It seems unbelievable but it is true. Also they slip. The 3s were clearly better in cushioning. ALSO THEY HAD CAUSED ME UNBEARABLE PAIN IN BOTH ACHILLES TENDONS! I was late, but I realized it, in fact others mention it too! Put it into AI to see it!!! It is astonishing how it is possible for them to have lowered the quality to such a level. So all these things they say to sell do not affect me anymore because simply I will not buy this brand again. The very serious problems they have, of course, they do not say, and the honest thing would be to withdraw them. In the purchase, also take into account the possible cost of visits to an orthopedist and also possible physiotherapy sessions to recover.
