Unparallel's stiffest downturned shoe, built for precision on all angles. The unlined synthetic upper provides a snug, secure fit without stretch. 4.2 mm RH rubber sole delivers exceptional edging on small footholds, while the extended toe rand rubber enhances toe-hooking friction. Highly tensioned heel with slingshot randing locks the foot in place for powerful heel hooks. A favourite among climbers transitioning from Five Ten Hiangles.
