I recently started running and was experiencing a lot of soreness after until I started running in these. You can really feel the support and forward motion, and my body feels great (as opposed to very sore!) after training now. Definitely buy a size down though. I'm usually a women's 7.5, and an Adidas 6.5 fits me perfectly.

I'm very happy with my purchase. I've had ankle surgery, and these are so comfortable. Wish they had more colors!
