The checkout menu lists the destination names in evidence, but the page does not say the list is exhaustive. “Ingresa tu dirección de envío para ver los métodos disponibles.” No country-specific cost, free threshold, or transit time was shown. Brand and product limits may block some shipments. The help page names Asics, Mizuno, and Wilson tennis racquets as examples of brand limits. The menu also lists “San Martín”; I omitted it because the label does not identify MF or SX. The test cart was removed after review. No personal or payment data was entered.

About this product
Adizero in Cobalt Blue gives the adidas Boston 12 a blue colour focus for its 2024 release. Cobalt is a vivid blue that contrasts clearly with white and sits well alongside grey or navy. Beige clothing offers a warmer pairing, while black keeps the surrounding palette restrained and allows the blue to remain the most prominent colour.
