Customer Reviews
Excelente tracción para trail de 25 km en barro y rocas.
Excellent traction for 25 km trails in mud and rocks.
Calzata più generosa senza essere slacciata. L’avampiede ha spazio sufficiente per lunghe distanze. La suola è aggressiva e performante. Ottima alternativa per chi trova il modello standard stretto.
More generous fit without being undone. The forefoot has enough space for long distances. The sole is aggressive and performing. Great alternative for those who find the standard model tight.
Enfin une version pour pieds larges sans perdre en performance. Le volume est bien réparti, surtout sur l’avant-pied. Le grip reste excellent. Idéale pour les coureurs à forte voute plantaire.
Finally a version for wide feet without losing performance. The volume is well distributed, especially on the forefoot. The grip is still excellent. Ideal for runners with a strong arch.
Versión más ancha que ajusta perfectamente para pies anchos. Sin puntos de presión ni roces. La suela es la misma que la EX 3 estándar, por lo que el agarre no cambia. Muy cómoda.
Wider version that fits perfectly for wide feet. No pressure points or friction. The sole is the same as the standard EX 3, so the grip doesn't change. Very comfortable.
