The ZERO GRAVITY products are desinged to to be as functional as possible yet as light as can be.  Models included are the ultra light yet tough Baltoro and the Mustang which has a medium weight upper, for added durability, and the Hi-Trail Lite Sole unit

The distinctive features of the models in the ZERO GRAVITY line are performance, comfort and material. They adapt immediately to the foot, guaranteeing a snug fit, thanks to the four zones with different degrees of padding (upper, FLEX-POINT SYSTEM, collar, tongue). 

The hallmarks of the whole ZERO GRAVITY line: the design of the upper, which provides extra strength and support to the side of the ankle; the anatomic heel support for improved fit and control while walking. In addition, there is an anti-abrasion reinforcement on the toe. 

The HI-TRAIL LITE sole is composed of a SHOCK-ABSORBING polyurethane midsole with a thermoform EVA insert at the heel and a VIBRAM® rubber outsole.
