La Sportiva Spire GTX Multisport shoes (46,5, black) - By using lightweight mesh and Gore-Tex Surround technology, La Sportiva has created an extremely well-ventilated shoe. Meet the Spire GTX multisport shoes from La Sportiva. The shoe comes equipped with aeration channels within the footbed and midsole through which heat and moisture can escape. That way, your feet will stay nice and dry on tough mountain runs. For traction, La Sportiva opted for the Vibram XS Trek outsole. To ensure a high level of comfort, they incorporated an Ortholite Mountain Hiking footbed along with a cushiony EVA midsole. To prevent the channels getting clogged, La Sportiva added close-mesh nylon as well. The comfortable lacing and pull-on loop at the heel add the finishing touches to the lightweight outdoor shoe from La Sportiva.
