It is an exceptionally light, stiff, durable sole, with an anti-slip insert in the toe and replaceable polyurethane heel pad to help get you through transitions. The Carbon Composite SoleÆ is compatible with the best pedal systems available, and includes a printed 10 mm lateral and fore/aft cleat alignment scale on the sole as well as the Look Memory EyeletÆ for easy cleat alignment and replacement. SIDI Heel Cup Inspired by SIDI motorcycle boot technology, the SIDI Heel Cup is an external, reinforced cup that stabilizes and supports the heel.

The SIDI Heel Cup also provides additional foot protection in the event of a crash. Triathlon Fit Tip: Size SIDI tri shoes by dress shoe size, not running shoe size.
