DESCRIPTION
DESCRIPTION
The Nucleus GTX trainers in grey are built for riders who demand comfort, protection, and style all in one. With a ripstop upper and technical fabric construction, they’re lightweight, durable, and ready for city streets, commutes, or weekend adventures. The asymmetrical closure with lock laces and webbing holder keeps your fit secure, while the rear loop makes getting them on quick and easy. Reflective laces and heel inserts give extra visibility when it matters most.
Inside, the Gore-Tex lining keeps your feet dry and comfortable in any weather, while D3O ankle protection, reinforced heel and toe, shift-gear guard, and TPU stabiliser provide confidence and safety on the bike. The Vibram Rubber+EVA sole ensures grip both on the pegs and on the pavement, making the Nucleus GTX Grey trainers a versatile, reliable, all-day choice for riders who want protection without compromising on style.
