Check the listing for details. Tuli's Heavy Duty GEL Heel Cups (PAIR) ALL Sizes Available. Color: Clear/Opaque, Condition: New. Listed at 19.99 USD. Tuli's Heavy Duty GEL Heel Cup Pair Provide additional thickness and support for athletic performance. The foot is a complex structure, impeccably designed for balance and mobility. So when we looked to deliver the best support available, we simply turned to nature. Bio-mechanically Designed Tuli’s® multi-cell, multi-layer design absorbs shock and returns impact energy just like the system naturally found in your feet. Upon impact, the heel cup bears down and rotates with the normal motion of the foot to absorb the shock of walking and running; keeping your feet, knees, hips and back in alignment for maximum comfort and performance. Ultimate Heel Pain Relief The #1 Podiatrist recommended Tuli's heel cup provides immediate relief from heel pain by cushioning the area of pain and elevating the heel bone to take pressure off of the Achilles tendon which lessens the tension and allows for a regaining of flexibility. Lighter, Softer, More Resilient TuliGEL™ is exclusively formulated to be lighter, softer and more resilient than other gels. Softer gel means better shock absorption and increased comfort with or without socks. It’s so light you’re likely to forget it’s there.
