Many men and women suffer from unsightly toe nails and are embarrassed by their feet. In order to hide them from their friends and family they often wear a full shoe, sock or paint over the damage to disguise it, often making it worse in the process.
These types of nails may be fungal, misshapen or permanently damaged. Perhaps you have damaged your nails playing sport and still want to play but wearing shoes is uncomfortable without a nail to protect your toe. It may be that you had nail surgery some years ago and are left with little bits of nail where the nail plate should be.
