I usually wear a 26.5-27 in New Balance, but these shoes fit perfectly in 27.5. I've kept them new in the shoe rack for about four years, waiting to wear them. There's some minor drying on the rubber parts, but it's at a level that shouldn't affect the appearance or functionality. These are lightweight, tough, functional, and highly adaptable trekking shoes. The uppers are made of high-strength polyamide nylon and suede leather, protected by a rubber rand for durability. The design, with a cut-out at the back of the ankle, supports light and agile walking. The soles can be replaced. With a firm sole and a shallow cut at the back of the ankle, these are modern Kletter shoes, strong on rocky terrain and varied routes. This time, stretch Gore-Tex has been newly used on the tongue, making the fit around the ankle softer and smoother, allowing for more secure and effortless footwork on rocky terrain. Despite being a 3E width, you can tighten them from the toes, making them one of the most well-fitting shoes in the Sirio lineup, and a lightweight, high-performance trekking shoe. Designed for Japanese feet and crafted with high Italian craftsmanship. ▼ Weight Approx. 590g (per shoe / 26.0cm) ▼ Materials ◇ Water-repellent Perwanger suede (1.6/1.8mm) ◇ Water-repellent high-strength nylon ◇ Rubber rand ◇ Gore-Tex liner ◇ Plastic soft insole ◇ Vibram MASAI sole ▼ Features ・Width: 3E ・Sole Stance: 6.5cm ・Suitable seasons: Spring, Summer, Autumn ▼ Vibram MASAI sole The angled block pattern provides grip on rocky terrain and uneven ground.
