Wedge or Lefties are shoes with a sole in the form of a wedge, such that one piece of material, normally rubber, serves as both the sole and the heel. Wedges for women are more common and often have a sole that is much thicker at the back than at the front, making them high-heeled boots or shoes. Unisol offers a wide variety of Soles in PU, TPR, TPU and Rubber for a wide variety of wedge style footwear for Women, including Sandals and Slippers.
