Testet around 2 month now, with and sometimes no reboot pants to compare after each 10km upto 30km running pass. I run around 70km per week trail and in my 40ies. I really feel low soreness after around 50min in A and B on max pressure. 240 very often . Sometimes i go down to 180 or210. Start 30 min on B max then A. Soreness and freshness is extreme high after Reboots pants use. Those times i testes without pants i really feel my legs sore and tired. I am 191cm so pants are on limit but you can move up and down and if focus on hips upper part you can turn down 1 chamber of the foot since that will twist foot if not fully covered i notice. and vice versa. I highly recomend this product.
