It can all be done without the gadgets... I thinkkkk.

Wear peds or any white ankle socks around the house as much as possible. At nite, smooth a lite layer of creme or vaseline on heels before putting on socks... Too hot with socks at nite, a lite layer of creme will not leave a greasy spot on bed linens when the socks are kicked off.
If all else fails, get you some medium grade sandpaper.... be gentle!! lololol
