This is a GRIVEL Air Tech New-Matic crampon, purchased new approximately 7 years ago in the first year of the Reiwa era (2019), and used about 4 times, with a frequency of once every two years. It's lightweight and durable, and comes with adjustable straps (uncut). I have always taken care of it after each use, so it's in beautiful condition for its age. The strap belts have never been cut or folded. It includes the GRIVEL crampon case and an accordion (unused and unopened) to reduce snow build-up on the soles of your boots. The original box and instruction manual are also included, so even beginners can use it with confidence. ⚠ Only compatible with mountaineering boots that have a heel welt. I have uploaded photos showing how it fits on my mountaineering boots (SCARPA EU44) as an example. Please refer to them. - Brand: GRIVEL - Model Name: Air Tech New-Matic - Color: Yellow/Black - Accessories: GRIVEL crampon storage bag, accordion, original box, instruction manual, and many other accessories - Design Features: Lightweight and durable construction - Straps: Adjustable straps (uncut)
