The ultra-stiff SH-XC 90 shoes have been designed with one thing in mind: racing. To this end, Shimano has employed all its top-end product expertise including its heat mouldable Custom-fit technology, which ensures a locked-in fit during hard sprints. Other features that will no doubt be appreciated by competitive riders include supple synthetic leather uppers that easily mould to the foot and the three-strap closure that further ensures a secure fit. This comfy upper is affixed to a rigid carbon fibre midsole for excellent power transfer, which is then sheathed in an outsole that features mud-shedding polyurethane lugs and removable metal toe spikes. This outsole construction delivers unrivalled traction in sloppy conditions.
