Motorcycle boots provide protection during crashes, foot-drags, and impacts. They also offer support against the forces driving through the pegs of the machine. Most riders consider boots the third most important gear, just behind helmets and suit. A boot has to allow a rider to feel the motorcycle and its controls, grip the motorcycle and not restrict the rider's ability to operate the machine.
All motorcycle boots, some more than others, have some structure to help support the foot and ankle and to help eliminate hype flexion or extension aw well as any torsional twisting of the ankle that can cause injuries. The us of different materials and the way those materials and internal structures are shaped and placed on a boot allow a boot to bend and flex at designated points. Heavy wear areas often have added protection, like the shift area on the top of the left boot and the insides of the ankle that contact the frame.
There are two main motorcycle boot designs: traditional boots and pivot – aka hinged – boots. A traditional boot design inherently has areas that can pinch and bind on the rider when the ankle flexes. With a properly designed hinged boot, there is never any binding or pinching. Most pivot boots have nearly zero break-in period and many riders race with the boots straight from the box, which traditional boots can take hours to break in. Some Alpinestars boots doesn't have an external pivot but instead has pivot on the bootie. To provide movement, the plastic outside structure has a V shape that allows movement of the foot up and down. Traditional non-pivot boot use relief cutouts in the plastic shell to allow flex. Other non-pivot boots strategically place flexible leather and synthetic materials in areas around the ankle to provide the needed flex and movement.
Many motorcycle boot manufacturers work with tire companies to find a sole material that grips the pegs well but doesn't wear out too quickly. The rubber compound of the sole must provide durability, traction and food feel, and it must also absorb impacts and vibration and keep these characteristics over time. If you wear out your boot soles, there are many options to replace them.
Many boots have vents to aid in cooling, but keep in mind that black boots on a hot day are much warmer inside than white, just like wearing a black helmet on a sunny day will cook your brain.
Try on motorcycle boots before you buy, there are small differences between models, even within the same company. These differences can be toe box height, midsole width and heel-cup shape and size. White boots heavy with plastic material will turn yellow – it's an inherit problem with white plastic, especially living tropical Thailand. Us a light detergent when washing and stay away from nasty chemicals.
