In terms of function, tropical boots, temperate boots, and cold boots are three categories, but they are called differently depending on the military type used.
Tropical boots, also called desert boots, mainly emphasize keeping the feet dry and improve comfort in high temperature environments. The inner lining is either a single layer of cordura fiber/special nylon cloth, and the better ones are replaced with super lining or coolmax. Such as sweat-absorbing and quick-drying materials; jungle boots can be regarded as the ancestors of tropical boots in some performances, but jungle boots may enhance the quick-drying performance.
Temperate boots, emphasizing that they provide waterproof and breathability in humid and rainy tropical environments. They are mostly made of Gore-tex lining and are effectively waterproof for 4-6 hours; they can be regarded as products between jungle boots, flying boots, and desert boots. It can be used in a desert environment, but the comfort is not high, and it is more suitable for watery environments and drivers (the cockpit environment is uncomfortable, and the feet do not move frequently, this type of boots is very easy to use); but not suitable In environments where the water depth exceeds the upper, it is difficult for this type of boots to dry out in a short time after being flooded.
Cold zone boots, based on temperate boots, have added warmth retention capabilities, which are sufficient to cope with low temperatures and stagnant water after melting ice and snow. They are also more suitable for pilots (mainly bombers) to keep their feet warm during high-altitude operations.
If you add the performance division, at most it will be a lightweight series made of multiple steel toes to improve safety or use new materials, instead of flame retardant materials made of flame retardant materials (but most military boots will use flame retardant materials Yes, there are not many special emphasis on this point); Adapt to the changeable terrain, such as mountain boots developed in the mountain environment, low-top or special-shaped soles, but this is more common in foreign military.
