Exer-Fit shoes burn 4x more fat than an ordinary shoe and have an airy mesh upper which enhances breathability, while the combination of anatomic arch support, BioFoam™ cushioning, and an ultra-lightweight, deep-grooved sole, absorbs and displaces shock to make burning extra calories a breeze. You really don't feel the 3.7 degree incline once you get used to them which takes no time at all.
I chose the pink/white leather but there are other colors and an array of standard sizes available.
If you prefer a non-athletic shoe, there are other choices too like the Exer-Flip, Exer-Luxe, Exer-Slide and more. There is even a 12 minute exercise routine you can download featuring Tracy Mallett to help you burn even more. The exercises can be done anywhere and really is a great alternative to those working in an office or at home and need a quick pick me up.
You can find Earth Footwear here but I purchase all mine at Planet Shoes.
