THE ROOT OF IT
Heel pain rarely starts in the heels.
The band under your foot, called the plantar fascia, is part of one long chain. It runs from your toes up through the calf and Achilles into the hamstring. When the calf and hamstring shorten, they pull on that band with every step, and the heel is where you feel it. That's why a good physical therapist starts at your toes, not your heel.
Tap to watch: a first session, toes pulled back.
The frozen water bottle works until you stand up.
The frozen bottle, the insole, the night splint. Each one is real help, for a while. They cool or cushion the heel, and by the next morning the calf and hamstring are pulling on it again. Many owners describe the same loop.

Heel in the hole, toes pulled back, held for you.
This stretch is one your hands can't hold.
Heel in the hole, toes pulled back, held for you.
Pull your toes back and down and the whole chain lengthens at once, arch to hamstring. Therapists call it toe dorsiflexion. With a towel the anchor at the heel is poor, the foot slips, and your grip quits before the stretch does. The patented foot hammock holds the heel and pulls the toes back for you, so you can actually stay in it.
"I found that they were very painful to grip and didn't create the toe dorsiflexion that was necessary to elongate the plantar fascia where EVERYTHING begins."

You set the depth, so your foot stops bracing.
When someone else drives a stretch, the body fights it. On the CastleFlexx you control the pull: ease in, hold, back off an inch if it's too much. Five minutes a day, before your shoes go on. That control is why so many owners in their sixties and seventies use it at home, in socks, before coffee.
