The EDEA Piano ICE is the Lightest Skating Boot available and represents a turning point in Skating and Skate Technology. The KEY NEW FEATURE of the EDEA PIANO boot is its patented shock absorption features. Every time a skater lands a jump, there is impact. The force of the impact depends on the weight of the skater and how the jump is landed. When a skater lands a jump, this force is estimated to be between 2 and 8 times the skaters actual body weight. This means that a skater weighing 75 lbs can land a jump with 600 lbs of force. This impact produces a shockwave, that moves up through the legs and the body. These waves increase force across the ankle, knee and hip and even the vertebrae. We at discountskatewear endorse the EDEA Piano ice skates as the latest step in skating technology, minimizing the impacts and maximizing your safety.
