Jeremy Scott Adidas wearing comfortable

Compared with adult shoes ,,children regardless of the design or the use of material needs more care and healthy design . Designers will look more into the innocence of a child and health ,we need to fully consider the child physical development and let them innocent rot diffuse ,lively personality to express and embody .
Excellent children design in each detail can let a person feel thoughtful humanization design and have great originality appearance innovation. So parents what needs attention ,in order for their baby to choose a pair of appropriate shoes ,beautiful ?First of all need to be aware of one point ,namely the different age stages of children with different gait characteristics ,therefore need to buy shoes on the standard adjust appropriately ,in order to meet the growth needs of the child .
In fact, buy shoes and selection of children ,not only in appearance ,wearing comfortable ,more be helpful for the child development and the healthy growth of children ,with foot growth rule and physiological characteristics.
On the whole in a comfortable, lightweight ,breathable principle, in addition the color ,pattern should be lively and bright ,with full of childlike child psychology . Material for feet Abundant blood vessels and nerves ,texture soft shoes will not oppress local neurovascular ,effect of foot development or causing foot deformities .
Therefore ,soft cloth shoes cloth shoes shoes is better ,having good air permeability ,soft, lightweight ,comfortable, convenient child activity also is beneficial for the foot growth. If the choice of shoe leather ,as far as possible selection of leather softness ,permeability good leather .
Choose to sheepskin ,pigskin or cotton cotton vamp ,for lining shoes ,instead of leather or plastic component made of shoes ,,so as not to damage the children foot tender skin. In addition ,the older children can choose to help a stiff shoes ,it is relatively soft shoes to help foot muscle bone ,joint in the developmental stages of children to maintain body balance ,,good walking posture ,but also on the four to ten years old children formed the different degree of inner toe to certain corrective action .
Soles of the best selection of non-slippery excellent performance ,,the bottom surface is soft sole ,should also be appropriate to consider the soles of the strong resistance to abrasion. Hard plastic ,recycled rubber or leather hard shoes for children lack of flexibility, especially in preschool children ,bones ,joints ,ligaments are In development period ,balance ability is poor ,the sole cause children overweight excellent mobility ,and easy to damage children ankle ligaments .
From the shoe inner sole ,some children Jiaoxin site will add a small raised pad ,when the choose and buy should also pay attention to the cushion is not suitable for any age child. Children wear shoes are not the best,, this is because it would reduce the arch stretching activity space ,and a hard bottom shoes is easy to cause the flatfoot .
But older school-aged children can choose ,when the cushion to support the foot when walking ,enhanced stability ,make children in walking ,running ,jumping ,avoid foot ligamentous sprain ,reduce the midfoot injury.
The heel many mothers might be imitated star children let the children wearing slightly the heel of the shoes ,this is not conducive to children .High heels make body center of gravity ,easy generation genuflect ,bow waist shape deformity ,but also can lead to foot arch hypoplasia ,the foot muscle ,ligament strain .
So ,should try to choose a flat heels .Tie in general ,lace-up shoes is more suitable for children to wear ,because the shoelace can be appropriately regulated shoes The loose ,can also prevent playing running shoes off.
However ,when the choice also need to consider the child age ,don way complex shoes hurt children .Elastic children foot muscles and bones are very soft ,narrow shoes tied foot muscle ,ligament of the development ,and even cause foot deformity, and too loose shoes will affect children walking and activities in the choice, should wear shoes can be inserted into a suitable,, not because the feet of children quickly, and deliberately buy big shoes .
In addition ,,never in the shoes of the code as the standard selection of children ,different brand children code number is different ,according to the child actual size ,try after purchase .
Children brand promotion in a superb collection of beautiful things of shoes in the market, choose a design close ,good quality brand children ,let the children get better care ,for many parents are very necessary .
