This is a premium two-piece sole with a high-traction moulded-rubber outsole and comfortable cold-blocking EVA-sponge midsole designed for outdoor use. The outsole is made of natural rubber and features an inner set lugs of designed for maximum any-angle grip and flex, while the outer lugs are designed for maximum lateral/medial support and wear. The spacing of the lugs and slight radius at the bottom of each lugs helps to release and minimize build up of mud and debris on the outsole during use. The toe bumper is designed to rise above the toe line to protect the toes and provide support to the entire toe box of the boot. The rear bumper is designed with a large rigid “kick spur” for easy-off convenience, plus rises above the heel bone (calcaneus) to provide maximum protection and support to the entire heel area. Lastly, the sole is designed with a wide base in the forefoot and heel to provide greater support and stability on a variety of rough terrains.The Haymaker’s non-pigmented gum rubber formula sole is slightly softer and more grippy on wet or dry surfaces. It also has a higher content of natural rubber, making it naturally more resistant to barnyard elements such as urine and manure.
