Developed as part of the Ra project, the Masai by TENAYA shares many of technical advances made in that shoe.

The major differences are that in the MASAI the design has been optimized for maximum efficiency on micro-edges. The lace-up closure means the volume of the shoe is infinitely adjustable, ensuring a snug yet comfortable fit. The Masai by TENAYA is the shoe of choice for vertical or slightly overhanging routes and boulder problems.

All the precision at the tip of the shoe: The optimally shaped asymmetric toe-box concentrates all the power of the foot into a very specific area, allowing maximum transition of force onto the tiniest of holds and providing superb control.
