I’m having a blast running in these shoes. I got them hoping they would help with my Achilles tendon problem. Wow, did they ever. At the gym I always had pain after about 30minutes of cardio work. Now with the Vibram Bikila LS it is almost perfect. I know, sounds like an infomercial. I run a bit more than 3miles on hard surfaces and I am loving it! They were one of the best father’s day gifts I have gotten..
