All Original S.W.A.T. footwear has one common root; they are all made on the same boot last. Regardless of the outsole design or the upper pattern, all Original S.W.A.T. boots are made on the same last. The last is the “form” around which the boot is constructed. It gives shape and structure and contributes significantly to the fit and comfort of the boot. Each company uses its own last and therefore, all boots fit differently. Our last was developed using the most modern computer-aided-design technology. This modern approach has enabled us to most accurately reflect the needs of today�s end user. Some products that are offered by older traditional manufacturers are using lasts that have not changed since the 1940�s. Since that time, the weight and foot shape of the average person have changed significantly. To provide the correct level of comfort and support, the last needs to be of a modern shape and design. The quality of materials and components makes a difference in performance & durability. High performance linings are important as they have to wick significant amounts of moisture away from the feet, approximately 1 pint every 3 hours. The appropriate use of 1000 nylon and breathable full grain leather facilitate this process. The heat formed heel counter is the most important component, ensuring the stability of the foot, and preventing slippage laterally and lengthwise. Lack of stability is the major cause of fatigue and injury. In a standing position, 50% of our weight is on the heel; this is increased by a factor of 3 or 4 when walking or running is undertaken. Shock absorbing materials can therefore play a big part in preventing fatigue and injury. There are several types of materials that can be used for shock absorption. We currently use two types, compression molded EVA and air. Compression Molded EVA is an inch of closed cell foam-injected under pressure. This by far is the most durable and effective material that we use for shock absorption. It does not hold memory and gives the wearer total foot support. This cushioning system is used in many different black boots as well as athletic shoes. The ideal use of "Air" is for indoor activities. This eliminates the environmental hazards met daily by a patrol officer. These hazards may cause a puncture or leakage in the "Air" cushion unit. This may eliminate the cushioning in this boot. However, "Air" does provide the wearer with excellent shock absorption and cushioning while standing for long periods of time. Support comes from a riveted sandwich lasting board that contains a steel or synthetic shank, providing both torsional and arch support, which are important where foot strike angles are uneven and extra weight is being carried. A removable contour molded innersole complete the support process, ensuring that the smaller muscles of the foot do no have to work excessively under extreme performance conditions. * Lightweight * Outsole Design & Construction * Closure Systems * Overall Strength Being obsessive about weight will generally lead to a reduction in durability. The art is to maximize strength to a point that it adds no extra weight. Simultaneously to create a balance between all components that will enable them to wear at approximately the same rate as excessive durability will cause an increase in weight.
