The Instinct VS features the same Lorica upper used on the Instinct Slipper which provides great flexibility and ensures that the shoes hold their shape longer than leather equivalents
The Lorica upper is built around the down-turned toe last of the Instinct family ensuring precise toe placements with high levels of feedback. Vibram XS-Edge ensures that your feet will stay planted on the smallest of edges and stiffens up the toe increasing responsiveness. Bi-Tension technology intimately connects the toe and the heel of the boot helping to increase overall performance which is guaranteed to last.
The Velcro strap keeps the heel of the shoe firmly secured to your foot even on the most demanding heel-hooks with the new toe rand design providing durable performance on toe-hooks.
