Tuli Heavy Duty Heel Cups

Comes as a pair. 
Tuli’s Heel Cups has a patented, multi-cell, multi-layer “waffle” design which absorbs shock and returns impact energy just like the system naturally found in your feet.  When you walk or run, Tuli’s Heel Cups’ waffle construction design bears down and rotates with the normal motion of the foot to absorb the shock.  And just like a spring, Tuli’s Heel Cups returns that energy back for maximum comfort and performance.
