Build up those leg muscles

These are perfect for running or jogging as the way the sole is built it works on certain leg muscles to strengthen your legs, along with cool colors too.

These are the most comfortable shoes I own. They take a bit to get use to as the back part of the heel is missing so you "roll" your foot from back to front as you walk. This is suppose to help strengthen your glutes!

Shape-ups are designed to help you strengthen your muscles, including your back, abdomen and calves. Shape-ups will help you lose weight and improve your circulation, creating a healthier you! It's easy to shape up with Shape-ups. Wear your Shape-ups everywhere and anywhere you walk (or stand), and your body will feel the benefits. Designed to improve your life by changing the way you walk, Shape-ups feature a unique soft kinetic wedge insert and dynamic rolling bottom to simulate walking on soft sand. With the comfort of Shape-ups, you will feel your heel sink to the ground as you step, roll forward as your weight shifts to its center, and push off with your toes. This movement will result in stronger leg, buttock, back and abdominal muscles as you stabilize your steps.
