The size? x Gel Citrek 'Base Camp' sneaker pays homage to the challenging expedition to Machu Picchu, one of the Seven Wonders of the World. This particular shoe, introduced in October 2019, is a result of a collaboration between UK-based size ? and ASICS, and it is part of a two-pack collection. Crafted with a combination of suede, breathable mesh, and rubber panels, the upper of the sneaker is designed to withstand the demanding conditions of increasing elevation. To ensure comfort and performance, Gel technology is incorporated into the heel, offering a responsive bounce, while the traction-ready outsole provides excellent grip on rocky terrains.
