Thanks to its carefully designed fit, it offers unique versatility: worn at the usual size, it is ideal for progressing without pain, while a tighter fit transforms the Spider into a true precision weapon, capable of effectively charging micro-holds. Designed as a hybrid model, it combines the precise support of a ballerina shoe with the practicality of a double Velcro closure for a quick and reliable fit. Its new two-part sole offers a major innovation: A taut yellow rubber sole that preserves the original shape throughout the life of the shoe and acts as a wear indicator at the toe. A front zone featuring No-Edge technology on the sides, which provides extra rigidity when flexing and better stability on small holds. Comfort is not neglected either: its rear pull tabs integrated into the upper avoid any uncomfortable seams on the heel, for a comfortable fit even during prolonged use. With its 4mm Formula Enduro rubber, the Spider guarantees long-lasting grip, whether indoors or on the rock. Its performance/comfort/price ratio makes it one of Andrea Boldrini's best-sellers, adopted by both beginner climbers and demanding regular climbers alike.
