These are high-cut shoes from Oboz. The slightly stiff sole made them suitable for a wide range of trekking and mountaineering activities. The soles still have plenty of tread left. There is no visible hydrolysis due to aging, but these are still used items. - Manufacturer: Oboz - Model: Traverse Mid (trekking shoes, approach shoes) - Color: Black x Green x Gray - Size: 28.0cm There is a sense of use in various places, but please understand that these are being offered as-is. Thank you for your consideration.
