Tallac uses a lightweight and breathable Cordura® upper with a stitch-free and fully welded construction for durability. Tallac BOA® has been updated with the PerformFit™ Wrap from the BOA® Fit System—designed to improve power transfer and efficiency while providing a micro-adjustable, precision fit you can adjust on the fly. A supportive and vibration-dampening midsole keeps things feeling calm and collected on the bike while the reverse hex traction in the toe and heel of the outsole makes easy work when hiking becomes necessary.
