My wife suffers from fat pad atrophy on the balls of her feet and needs specially shaped cushioned pads to stop the formation of callouses and ulcers. She has always used the ‘firmer’ Hapla felt and just started using the soft wool felt. She is so happy with these, the comfort is much better and it’s actually worth the boredom of me stencilling and cutting 20 pads at a time to keep her going for a week or 2. Thoroughly recommended.
