Step RV (regular volume) is a shoe for beginner/intermediate climbers designed as a step up from a rental to help those who are newer to climbing. 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. 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/step-blossom-white-so-ill-m-35-w-5-so-ill-5365112.jpg?v=1772235254","https://cdn.shopify.com/s/files/1/0424/1145/files/step-blossom-white-so-ill-m-35-w-5-so-ill-1866520.jpg?v=1772235254","https://cdn.shopify.com/s/files/1/0424/1145/files/step-blossom-white-so-ill-m-35-w-5-so-ill-3505656.jpg?v=1772235254","https://cdn.shopify.com/s/files/1/0424/1145/files/step-blossom-white-so-ill-m-35-w-5-so-ill-5109782.jpg?v=1772235254","https://cdn.shopify.com/s/files/1/0424/1145/files/step-blossom-white-so-ill-m-35-w-5-so-ill-4337191.jpg?v=1772235254","https://cdn.shopify.com/s/files/1/0424/1145/files/step-blossom-white-so-ill-m-35-w-5-so-ill-7529189.jpg?v=1772235255","https://cdn.shopify.com/s/files/1/0424/1145/files/step-blossom-white-so-ill-m-35-w-5-so-ill-7715435.jpg?v=1772235255","https://cdn.shopify.com/s/files/1/0424/1145/files/step-blossom-white-so-ill-m-35-w-5-so-ill-9955295.jpg?v=1772235255","https://cdn.shopify.com/s/files/1/0424/1145/files/step-blossom-white-so-ill-m-35-w-5-so-ill-6679364.jpg?v=1772235255","https://cdn.shopify.com/s/files/1/0424/1145/files/step-blossom-white-so-ill-m-35-w-5-so-ill-4897894.jpg?v=1772235256"],"price":139,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:48.505Z"},"share_url":"https://firestarter.network/l/lst_GKmwz0Yz","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
