Tuli’s Dual Density Heel Cups (previously known as Polar Bears) are designed specifically for heel spur sufferers. The conditions of heel spurs and plantar fasciitis are often confused but we understand the difference. Pain from plantar fasciitis is typically felt in the arch of the foot plus the heel. Heel spurs are felt more directly in just the heel of the foot. If you’re suffering from plantar fasciitis please find our Classic and Heavy Duty Heel Cups directly targeted for that. Tuli’s Dual Density Gel Heel Cups combine state of the art TuliGEL with our multi-cell multi-layer shock absorption design. We collaborated with podiatrists to create a soft light and comfortable heel cup that cushions your heels for proper support. They are supportive yet flexible enough to fit in most closed-toe shoes. These latex-free silicone gel heel cups contour to the heel for greater support and comfort. The blue center acts as a cradle to distribute pressure to the outer edges of your heel and away from your injured area. Should be worn with shoes. Sold in pairs.
