Ski technique changes over time to become more efficient, more powerful, more competitive. Same for equipment. Skiathlon , aka Combi boots, were considered very specialized for Skiathlon competitions or for lower cost and performance entry level gear. But as cross country classic racecourses have become more demanding many of the world elite are donning Skiathlon boots for a pure classic race. And this makes the good old Combi boot no longer a poor cousin but perhaps the optimal ski boot for classic skiing. The Fischer RC3 Combi boot has all these attributes but at a price that is easy to get into.
