Boots RESPONSIV ULTRA Shoe
Details of RESPONSIV ULTRA Shoe
Description
Underfoot the comfort word still reigns. The midsole is a full injection moulded system, giving long term durability and performance with exceptional rebound quality. Perfect for long days or multi-day trail. Shape is also important and the rolling sole profile allows a natural transition from heel, midfoot or forefoot strike. To keep the weight as low as possible we removed rubber from where it is not needed, you still get 4mm tread depth over the key grip areas, but the sole unit is 50% lighter than a normal sole.
Allowing you to balance lacing pressure over the top of the foot we developed the M-Lock band, this will allow you to have laces under less tension but still maintain foot hold on non technical terrain.
