What makes Frog Legs EPIC Soft Roll wheels different?  

Wide Sloping Sidewall Tire: Our arced tread design ensures the area contacting the ground is spheraical. A ball-shaped tire will pivot and roll much easier than a straight edge that gets caught. The extra girth distributes the downward pressure so the wheel maintains higher floatation and does not sink into carpet and other surfaces.

Custom High Resilient Urethane Tread: Other "polyurethane" treads contain recycled material or are infused with water creating a "foam". Frog Legs treads are spun-cast from virgin base chemicals. Use of recycled materials results in harder tread with minimal rebound. A foam contains microscopic air bubbles which absorb moisture. Moisture can increase weight up to 25% and reduce rolling efficiency significantly.

Highly Resilient: Like a super ball our tread bounces back when compressed to minimize energy loss and absorb vibration.

Improved Mobility: Case in Point: The Scooting Rock: A hard wheel will push a loose rock toward the center where it wedges and turns the wheel sideways. The EPIC wheel will absorb part of the rock, holding it in place and rolling over it. Studies prove our wide wheels traverse 21% more obstacles.

Clean, Quiet & Smooth: EPIC solid urethane will not absorb water so there is no dirty water tracked inside. The high-resilient material eliminates the "ticking" sound from tile.
