Provides awesome comfort, breathability & ventilation Featuring a slightly roomier high-performance fit, combined with mesh panels, the Specter provides awesome comfort, breathability & ventilation. The sole has great stiffness for efficient power transfer from your legs to the cranks, & is designed to give this stiffness without adding a high amount of weight. The high performing shoe is then finished off with a two-way adjustment boa for a secure fit, & a 2 & 3-bolt cleat system.
