There is a saying that high-heeled shoes, pointed shoes, thigh boots, lace-up sandals and other possible health problems, flat shoes are best for the feet. Is this real?
Select shoes must pay attention to the design of the sole, too thick, too heavy, too light, too stiff are not in line with human physiology, choose shoes with appropriate height, elasticity, and suitable materials are suitable for long-term walking. Don't wear shoes wrong, flat shoes that feel comfortable may not be safe, and not ideal for all occasions.
Foot force principle
The human foot is arched like an arch bridge, which is a guarantee of body stability. The arch of the foot is an integrated system of joints, ligaments, and muscles. Its bending and elasticity can adapt to uneven ground and play a role in load-bearing and shock absorption. Our feet bear the weight of the whole body. Any change in the physiological arc of the arch will seriously affect the weight-bearing function of the dome, as well as the maintenance of walking, running and body posture.
The contact area between the lateral longitudinal arch of the foot arch and the ground is large, which increases the stability of the human body when standing and exercising. The medial longitudinal arch has a greater curvature, which makes the foot more elastic and can offset part of the impact during exercise. The transverse arch is the metatarsophalangeal joint formed by the phalanx and metatarsal bones in the anatomy of the foot bone. During the movement of the human body, the metatarsophalangeal joint flexion and extension produce a forward pushing force.
When a person usually walks, each foot must go through the steps of stepping on the heel (heel landing), rolling (the centre of gravity moves forward, and one leg is in the swing phase), and pedalling (the metatarsophalangeal joint flexes the toe pedal off the ground). The arch of the foot allows gravity to be conducted forward from the ankle joint through the talus (the bone that bears the weight of the body, the bone at the ankle and the related part of the calf bone), dispersed to the small head of the metatarsal bone, and passed back to the calcaneus, cushioning the body The impact, protect the brain and internal organs from shock.
Changes in the shape of the arch of the foot will affect its physiological function, and in severe cases will cause health problems. For example, when wearing high heels, the sole flexes and the arc of the arch decreases, which makes the ankle joint loose and unstable, and can be used for lateral movement, significantly increasing the chance of sprain. Although flat shoes don't have this concern, they may still have other problems.
The impact of several types of flat shoes on health
Platform sandals are not as comfortable and safe as they seem. The thick and hard sole prevents the metatarsophalangeal joint from flexing and usually extending during walking, which hinders the process of gravity transmission. The stable triangular structure of the arch of the foot also disappears, replaced by a flat structure, which may have feet after standing or walking Discomforts such as fatigue and pain.
Too thick soles also cause the centre of gravity to move down, and it is easy to lose the centre of gravity when walking, and may accidentally sprain and fall. And some thick and light soles cause the person's centre of gravity to be biased, which makes people feel top-heavy. So thick-soled shoes are not synonymous with safety, "stepping on stilts" is also a technical activity.
Snow boots, which are also flat and have sole high hardness, have low midfoot stability due to lack of support for the arch of the foot. The flat single causes the arch of the foot to be significantly impacted, which can easily cause fatigue of the hip and ankle joints and Achilles tendon. Lesions. Moreover, due to the relatively large internal space of the boots, there will be a sure slip in the shoes after wearing, the shoes do not follow the feet, and the toes are forced when walking, making the tendons and the fascia of the soles tight, quickly causing fasciitis and tendonitis, making Foot strain.
There is no difference between wearing ultra-thin flat shoes (ballet shoes) and walking barefoot. The flat sole does not conform to the physiological arc structure of the arch of the foot. When walking, the impact of the landing will go from the heel to the spine along with the leg bones, which not only accelerates the degradation of the ligaments of the sole, causes heel pain but also causes the ankle, knee, and hip Strains on joints and waist.
BEITE flats soles are made of closed-cell foam. This material does not absorb water, so it is easy to clean and is not conducive to the propagation of bacteria or fungi. But the hydrophobic properties may also cause discomfort when sweating. Due to the soft texture and thoughtful design, BEITE can well disperse the pressure of the sole. Due to the physiological characteristics of the arch of the foot, the utterly flat design does not bring protection to the arch of the foot. On the contrary, a sole with an arch pad and a heel with an appropriate height can increase the stability of the flat shoe.
