I ripped my plantar fasciitis tendon while jumping recently in master's events (I'm 70). My sports doctor recommended this product. "Miracle" is not too strong a word here! Earlier, I was crawling around on all fours (such was the pain). Yes, that was a couple of weeks back, however, the pain (particularly getting up in the morning) is nearly unbearable. With these clogs, I slip them on and I'm off and running (well, walking briskly). The doctor himself (a marathoner) says he wore his clogs in his office for three years. Life is nasty, brutish and short: no need to hobble around on sore feet, on top of that.
