VIVOBAREFOOT Primus Trail Knit FG Men's Size 42 OBSIDIAN (Black) Purchased in March 2025 from the official online shop. Used only once (for about 6 hours) in low mountains. I've bought other shoes and don't use these much, so I'm selling them. No box. I have washed the entire shoe before listing, but please understand that these are used items. Immediate shipping available. Please refer to the official website for specifications and features. Thank you for your consideration.
