So I read review after review about these compression pants Annette told me about… Almost every single review started with total doubt that they did much … And ended with a firm commitment to them. The reviews especially discussed the benefits for recovery time after a run and how they felt better when they had to do back to back runs. I am sold! Now all the reviewers were runners but I believe they will provide benefits for hiking too. The idea is the increase blood flow and stabilize knees, hips, and core. Perfect! Only concern as I order them is the extra weight for pack when not wearing them and the heat when wearing them. I decided on the full length to help with shin splints and calf cramping which I get sometimes. Rule is if I add something to the pack I need to remove something… Ugh.
