New model for this year (Do not check this option if this model was listed as new in last year's Gear Guide)The SL Sintesi GTX is designed for serious hikers who are looking for a precision fit, with an emphasis on lightweight construction, stability and protection on variable terrain. The IMS-1 Internal Midsole System in this boot features an anatomically-shaped lasting board with an internal 5mm layer of EVA. This results in immediate comfort (without having to be broken in) and reduced weight. Another benefit is that it keeps the hiker low to the ground, weight is evenly distributed, and lateral and frontal slippage is controlled. The 1.8mm suede upper features rubber heel and toe protection and the Vibram Mulaz® outsole features a climbing zone at the toe for precision. The precision lacing system extends further to the toe for a more precise fit.
