Dynafit says about the Neo PU
For ski touring enthusiasts who seek the performance of a polyurethane boot with an extremely minimal weight. This boot offers the same technical solutions as the NEO PX model; however, the upper and shell are made of polyurethane. The result is a progressive flex and an outstanding downhill performance at a weight that Pebax boots normally do not achieve. Compatible with all ski touring bindings on the market. Available with the Custom Ready (CR) thermo-moldable boot liner for immediate comfort, better insulation and a longer life cycle. The lower shaft height and softer materials adapt superbly to a woman’s foot.
