Love these sneakers.  I do cardio, toning, strength, etc.  so running shoes aren't good for these workouts.  I do plyometrics and can get shin splints when I don't have the right shoes (and even sometimes when I do).  I bought a pair of Asics trainers that were heavy and too high on the sides and I got shin splints.  I read about these in Women's Health as a top performer trainer for intense workouts and bought them.  I have been wearing them for almost two months and I am very happy with them.  Even my co-worker bought a pair.  I had previously worn Under Armour trainers which I really liked too but they stopped making them.  It is hard to find training sneakers and running sneakers aren't cut out for my workouts so I'm happy I found these and hope they don't stop making them!
