AERON redefines XC performance through advanced construction and precision fit. The ripstop upper with rubber bumpers offers protection without added weight, while dual NUUN 001C dials and internal Firmor reinforcement ensure secure, responsive support. A fast-adapting instep and UNUM tongue deliver a pressure-free fit, complemented by a tool-free heel adjuster for fine-tuned stability. The sole, with stiffness index 11 and generous rubber coverage, offers powerful traction and efficient energy transfer.
