The Spire’s rounded toe box and relaxed-foot fit make it an extremely comfortable shoe. It has a slight asymmetrical shape, creating some tension and focussing the power toward the inside front, yet the shoe doesn’t seem awkward to novices. The toe profile will limit the shoe’s ability in pockets and thin seams, but makes for great rubber coverage on slabs.

A flat profile suits long routes and cracks. Curved shoes allow precision and good edging. Hooked shoes are down-turned and tensioned, for power to the toe on steep or overhanging routes.
Highly asymmetric shoes allow more precision and focused power. Symmetrical shoes are more comfortable for all-around climbing.
Stiffness is provided by the type of sole and the tensioning system. Softer shoes allow more precision. Supportive shoes prevent fatigue.
A highly tensioned shoe tends to push your foot forward to create a powerful curve in your toes.
