Foot Petals Heavenly Heelz multifunctional shoe cushions are crafted of Technogel -- a patented, revolutionary gel like no other. Its 3-dimensional shock absorption diffuses pressure broadly across the foot, reducing stress on all pressure points. It will never harden, crack, yellow or develop odors. Technogel provides virtually invisible comfort that never goes flat and will outlast your shoes. Guaranteed. Heavenly Heelz will help prevent painful blisters on your heels, and can also be used at the inside top of your shoes to ease friction. These foot-saving Foot Petals may be used as back-of-heels cushions to help keep your heels from slipping in and out of your shoes. Heavenly Heelz can also be used at the tops of mules, flats or boots. Heavenly Heelz helps with size and fit issues; shoes that may be slightly too large but absolutely must have them anyway! Plus, they'll help prevent hosiery from running. They're reusable from shoe to shoe, and you can simply wash them with soap and water to restore adhesiveness. How's that for value?
