Synxgeli Gel Heel Socks have been designed specifically to provide a barrier for any bone deformities at the back of the heel that may be aggravated when wearing shoes as well as protecting against cracked heels. They cushion, protect and relieve soft tissue, bones and joints against unwanted stress, providing optimal comfort and pain relief. We also recommend using the heel socks at night-time directly after applying emollients and creams for best results when treating cracked heels.
