Sprint faster. Ruck harder. And look cool doing it. The new standard in functional fitness footwear with 3X Support™ and 3X Stability for all three (3) of your arches, making them the best workout shoes for men and women ever created.\nFeatures\nEngineered Warp Knit & CORDURA® Ballistic Nylon UpperThe forefoot is constructed using an engineered warp knit technology which provides a seamless one piece vamp and toe cap while offering areas of reinforced strength and other areas of breathability and flexibility. The lace area, midfoot and heel is made from two panels of CORDURA® Ballistic Nylon — offering the toughest Special Forces grade abrasion resistance against the stresses of rope climbs. This CORDURA® also provides superior midfoot and heel support during dynamic movements.Anatomically Molded TPU Heel CounterAnchors your foot with a supportive, injection molded heel counter that stabilizes your heel when you're doing dynamic, load bearing exercises.Lace-Lock EyeletsExtra top eyelets can be used to create a tight heel lock — commonly called a runner's loop or lock lace — that prevents heel slippage and excessive movement around the ankle. Wide Toe BoxGenerous forefoot area lets your toes breathe. Over time and distance doing the work at the gym or anywhere you're training, your feet will swell. This extra space, along with the breathable and flexible knit, reduces the friction that can occur if your feet rub against the insides of your shoe.Custom High Density InsertDense, PU foam insert custom made to fit the contours of the foot supporting all three (3) arches of the foot — yes, you have three arches in your foot (the medial longitudinal arch, the lateral longitudinal arch and the anterior transverse arch). Versatile Heel-to-Toe DropClassic powerlifting shoes have a 20mm+ heel-to-toe drop (and meant for nothing else), running shoes are all over the place (according to the latest fad), other functional fitness trainers ","images":["https://cdn.shopify.com/s/files/1/0275/4985/9940/files/black_gum_spearhead.jpg?v=1767722379","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/ballistic-trainer-black-gum-sandbag-rob.jpg?v=1767722380","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/ballistic-black-gum-ruck-squat.jpg?v=1767722382","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/ballistic-black-gum-rucking.jpg?v=1767722384","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/ballistic-black-gum-lunge.jpg?v=1767722387","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/ballistic-black-gum-barbell.jpg?v=1767722388","https://cdn.shopify.com/s/files/1/0275/4985/9940/files/ballistic-trainers-black-gum-rpc-sprint.jpg?v=1767722390"],"price":99,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T14:55:59.292Z"},"share_url":"https://firestarter.network/l/lst_5Jn0fsYB","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
