The Manta Pro is now built on the FT last, one shared with the Charmoz, that offers a more technical closer fit which offers better support on steeper, rougher terrain whilst enhancing sensitivity when scrambling. The AutoFit collar and Flex Point Zone provides high levels of comfort and allows the foot to flex naturally when walking without sacrificing support. Underfoot performance has been improved with the new Pentax Precision XT sole with Activ Impact Technology. Basically the sole has been designed to absorb ground impact, providing better shock absorption and energy release; it gives you a spring in your step! The lug pattern is deeper and more aggressive with a dedicated flat climbing zone around the toe area. The Manta Pro GTX has a massively improved TPU crampon plate which sits on top of a durable PU shock absorbing insert, and an additional one under the forefoot. With more progressive flexing the Manta Pro is far more comfortable over longer walking distances, eliminating that flat footed heel toe action often found in stiffer boots. The uppers are constructed from reversed Suede leather and feature the Speed Lacing System, each lace point has a roller to keep lace tension smooth and even. A full rubber rand protects the uppers from abrasion and scrapes. Scarpa have re-designed the Manta to produce an all-round B2/C2 boot that is perfect for UK mountaineering. Suitable crampons would be the Grivel G12 or G14 with New-Matic bindings.
