Stay protected and comfortable when the weather changes
Wet roads should not mean arriving with soaked feet or spending the day in heavy motorcycle boots. The Sidi Nucleus Gore-Tex combines dependable wet-weather protection with the flexibility and walking comfort needed for commuting, touring and everyday use.
Its GORE-TEX membrane provides a high level of waterproof protection while remaining breathable, allowing sweat and water vapour to escape. Fortex gives the shoe supportive structure without stopping the foot from flexing naturally, while D3O ankle protection, reinforced heel and toe areas, and gear-shift protection add motorcycle-specific coverage.
Underfoot, the Vibram rubber sole provides dependable grip and durability. This gives you a hard-wearing sole that is well suited to walking and regular use away from the bike, not just time spent on the footpegs.
