The new Scarpa Manta Tech represents the 7th generation of this iconic four season mountain boot an award winner over many years and always moving forward and improving yet retaining the comfortable fit, reliability and versatility people have come to expect from this great boot. The key changes for this latest development of the Scarpa Manta however, have focused on the upper, where lines have been cleaned reducing stitching and materials to facilitate the updated cosmetics giving the new Manta Tech GTX a much broader appeal to the global line of mountaineering.  Another key update has been to use of high performance GTX Duratherm, which will allow the boot to perform at a higher altitude and in colder conditions than previous generations, a point Scarpa feel will be especially appreciated on the Woman’s version.Scarpa Manta Tech GTX (40/46) Features: Suede Water Resistant 3mm Perwanger GTX Duratherm Insulation Gore-Tex® Insulated Comfort Footwear Lining Pentax Precision XT Vibram Mulaz S Outsole Partial TPU Rand Much Loved FT Last Weight: 880g
