4. air permeabilityPermeability are not only limited to the uppers, soles also calls for breathability. Because Outdoor Signage during normal wear sneakers, one foot skin temperature can reach 34~35℃ and in Outdoor Signage during intense exercise, the temperature will reach 43~49℃ in addition, outsole with grooves designed the rougher, more complex and greater friction with the ground, heat tends to be higher. Therefore, the breathability of the sole design is very necessary, but taking into account its waterproofness, Outdoor Signage, most likely at the transom, apply a layer of breathable waterproof glue, or using United States wL. GORE's GORE TEx material. 5. supportSupport is one of the more complex issues, specifically through the shoes tight chunky design, strong support to keep the foot on the human body. Design of this retrenchment, can overcome foot around scattered forces, thus ensuring the upward support force. General hard support chips (TPU) stretching from the shoes, waist to heel, plug or at the end of Outdoor Signage between the outsole and the insole, smooth supports, fixed effects on the foot, but also prevents the movement of a sprain.6. shock absorbersPeople walking in the Outdoor Signage bearing the State, roughly walked 600~700 steps per kilometre.
This means that each mile walk, nike air structure triax 91 cheap one foot to be under 600~700 gravity impact, intense exercise, it will have a bigger impact. Anyone doing statistics, when a man run in Outdoor Signage, feet touching the ground moments by ground impact will reach 2~4 times the body weight. If the shoe excellent shock absorption system to ease the impact, will make your feet feel exhausted and will also impact on the brain. Under normal circumstances, used to be resilient in the background (such as EVA, PU) or embed it in your Outdoor Signage outsole with heel flexible gaskets (such as EVA, PU) to reduce the force of impact. Meanwhile, you can achieve the effect of energy is lost (energy returned refers to the soles in Outdoor Signage to the ground after the impact, through compression of an elastomer to absorb the kinetic energy, and later, in Outdoor Signage before it was off the ground, due to elastic body shape of recovery and return energy to the wearer, make the wearer to run faster or jump higher).7. anti-sprainsHuman's foot is made up of 26 bones. Man's walk is a very complex and coordinated movements of the bones and muscles of the scientific process, feet from touchdown to lift it off the ground, the friction of an upward momentum and move forward, in Outdoor Signage foot strikes the ground the moment, subject to a great deal of momentum,
in front of the Outdoor Signage off the ground, cheap new balance 576 it is necessary to exert some force to get the friction on the ground. In Outdoor Signage this a process in the, analysis people feet of movement process is such of: 80% above people of feet is to heel outside side first with to, at heel axis slightly to outside oblique, with to Shi feet by a is big of momentum, it natural to to within flip, to dispersed ground impact caused of on feet joint of hurt, last heel axis from to outside oblique location turned to vertical ground location; in Outdoor Signage lift away from ground Qian, each related muscle group and the joint contraction tension, To provide the forces on the ground, this time axis perpendicular to the ground with the heel position was relocated to the external oblique position to provide forces. In Outdoor Signage, a process, usually will be two conditions: excessive and flip is not enough. If feet landing Hou to within flip Shi, heel axis had has vertical oriented within oblique, so in Outdoor Signage feet away from to Shi, it too late adjustment to outside oblique location, makes muscle bones failed to do full prepared, easy caused movement sprained to overcome feet bow Xia collapsed of flat foot easy appeared movement sprained of problem, soles General design into double density of elastic body, in Outdoor SignageFollowed by the medial side of the sole,
