Oh yes.... I know all about sore heels, and I'm not in a wheelchair. Mine get sore intermittently and hubby had nasty heel blisters when he had his knee operation.

Heels are particularly vulnerable to pressure areas because there's very little soft tissue between the bone and the skin to absorb pressure. There are some things you can do to help ease the pressure.

During the day you should:

*Examine your heels every day to ensure no blistering.
*Use moisturizer on your heels twice a day, but don't massage the skin..
*Some hospitals apply a transparent film dressing to the heels to help prevent friction, you could try that.
*Wear socks during the day to help prevent friction (remove at bedtime).
*Wear padded sneakers or shoes that fit properly when in the wheelchair
*Move your feet regularly to maintain a good blood supply

At night : Place pillows vertically under the legs to keep heels off the bed surface.

You could also try gel pads or memory foam pads (like wheelchair cushions) to rest your heels on

I hope that helps.
