I use these shoes for my cardio pilates routine daily, they help keep my spine aligned correctly during all the bouncing around, whereas I used to constantly have to 'remind' myself to stand correctly for the positions. I swear these shoes have improved my balance and posture already, and I've only had them a few weeks! I noticed a difference the first day I used them. They are awesome for both cardio workouts and walkin the dogs! I would recommend them to anyone, but especially those with back pain/issues due to poor posture. These shoes will help straighten you right out! They have the added benefit of being Vegan (i.e. cruelty free) which I didn't know when I bought them, but only made me love them more!
