{"type":"firestarter.listing","listing":{"id":"lst__RhjoTVQ","product_name":"Start","category":"Climbing Shoes","description":"DESCRIPTION:\nA rental that’s too good to be a rental. Designed with Fred Nicole on a flat last with a slightly downturned toe, Start RV is a shoe for beginners, but we’re calling it a performance rental shoe. Originally designed as a rental option for climbing gyms, Start RV has the shoe size laser-etched into the heel rand and includes snaps on the pull tabs to keep the pairs united while in storage. This model features a single piece, unlined, durable + comfortable vegan microsuede upper with a padded mesh tongue and elastic band for easy entry. The closure is a single z-strap to keep things simple. The midsole is comprised of a proprietary pressed fiberboard extending from toe to heel to provide stiffness/support. There is a break point in the heel tension rubber for increased comfort as well as a second toe rand rubber layer for increased durability/longevity. The outsole is composed of a proprietary rubber and includes a split for flexibility, making it a great shoe for all types of climbing.","images":["https://cdn.shopify.com/s/files/1/0424/1145/files/start-so-ill-m-45-w-6-so-ill-782926.jpg?v=1732549155","https://cdn.shopify.com/s/files/1/0424/1145/files/start-so-ill-m-45-w-6-so-ill-857519.jpg?v=1732549155","https://cdn.shopify.com/s/files/1/0424/1145/files/start-so-ill-m-45-w-6-so-ill-552633.jpg?v=1732549155","https://cdn.shopify.com/s/files/1/0424/1145/files/start-so-ill-m-45-w-6-so-ill-537777.jpg?v=1732549155","https://cdn.shopify.com/s/files/1/0424/1145/files/start-so-ill-m-45-w-6-so-ill-172309.jpg?v=1732549155","https://cdn.shopify.com/s/files/1/0424/1145/files/start-so-ill-m-45-w-6-so-ill-739688.jpg?v=1732549155","https://cdn.shopify.com/s/files/1/0424/1145/files/start-so-ill-m-45-w-6-so-ill-736647.jpg?v=1732549155"],"price":99,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:48.511Z"},"share_url":"https://firestarter.network/l/lst__RhjoTVQ","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
