Product description
The Sidi Crossair HD Enduro Boots - Black/Black are part of the latest collection from Sidi.
Purpose-built for the extreme demands of hard enduro and super enduro riding, the Sidi Crossair HD Enduro Boots deliver exceptional protection, lightweight performance and outstanding traction across challenging terrain. Weighing approximately 1,700g per boot in size EU 43, these specialist off-road boots combine the strength and support expected from Sidi with a remarkably lightweight construction. The durable microfibre upper incorporates an internal nylon and fibreglass-reinforced exoskeleton, providing structural stability and protective support without unnecessary bulk. Strategically positioned impact protectors and an innovative three-point anti-hyperextension system help protect the foot and ankle during demanding technical riding. The ultra-slim inner profile improves contact with the motorcycle, while heavy-duty adjustable buckles ensure a secure, personalised fit. A standout feature is the directly stitched rubber enduro sole, which takes inspiration from trials footwear to deliver exceptional grip both on the footpegs and when navigating difficult terrain on foot. Finished in a stealthy Black/Black colour scheme, the Crossair HD is engineered for riders who demand maximum control, durability and confidence in the toughest off-road environments.
