Performance cycling shoes designed for this system typically feature stiff soles with minimal tread, optimized for riding rather than walking. The larger cleat design uses a three-bolt attachment, providing a more secure connection compared to 2-hole systems. Popular 3-hole cleat brands include Shimano SPD-SL, Campagnolo, and Time.
