Provides stability on snow with adjustable straps and sharp crampons. Thank you for looking. My spouse and I purchased these new this season and used them twice, at Zao and Goshikinuma. There are no issues with use, but there are scuffs on the frame and chips on the claws that come with normal use. I have included photos. Renting also costs a fair amount, and it's inconvenient not to be able to move freely, so having your own is more convenient. I think this is a good deal as it is a set of two. There is no carry bag. The instruction manual is included. I will be on a business trip from the 16th to the 19th of next week and will not be able to ship. Thank you.
