soft good. are easy to clean andHardness, density, tensile, tear,
elongation. Disadvantages: easy to corrosion is bad for the environment,
more easily at high temperatures, easy to shrink. TPR: TPR aggregates
after the hot-melt-casting process, often used to jog, walk, the shoes
midsole, outsole. Advantages: easy to shape, cheap; cons: poor
materials, wear (not wear), poor flexibility, bending low (no folding),
shock-absorbing capacity air jordan 6 retro uk
. Performance comparison: TPR large, relatively heavy, flexible,
abrasion resistance in General. Large proportion of rubber bottom, but
softer, very wear-resistant, strong grip, but poor flexibility, usually
used on indoor soccer shoes and casual shoes. EVA bottom is light,
resilient, just wear a long elastic decreases become practical. PU, MD
bottom elastic, and permanent deformation and movement is more flexible
and comfortable, the
proportion of small, very light, so the use
of broader, (PU MD density greater damping effect is better, but it is
also relatively heavy). Big negatives are rubber, wear-resistant
anti-slip. Price Shang-TPR most cheap PU=TPRx2 times around MD=TPRx3

(ii) sneakers air jordan 4 retro uk
surface material classification and performance introduced: sneakers of
fabric about has PVC, and PU, and Niu Ba, and Super fine fiber, natural
skin, and network cloth, several big class, following respectively
briefly Description: PVC: most more cheap, texture poor, not Hardy, not
resistance folding; products without PVC made fabric. PU leather and
nubuck Pu: is the material most commonly used on the market today. PU
leather is soft, elastic, feel good, how Microfiber surface: soft
texture, the texture is uniform, very close to
natural leather
and more uniform than natural skin thickness, elasticity is more
balanced, a leatherette class is one of the best materials.The cheapest
prices at more than 60 dollars per yard, good up to more than 200 Yuan,
at present most of our shoes on the use of such materials. Natural skin:
is generally approved material, it is breathable, soft, split, folding,
cold, durable, flaws is flawed, the pores,Nonstandard shape is not easy
to spot. Which is one of the favorite natural skin; shoes with leather
cowhide, pigskin, suede, ostrich skin, crocodile skin, snake skin, and
many other species. General use leather sneakers. Leather can be divided
into the first layer second layer of skins and leather, suede or grain
leather, second floor known as split leather or patent leather, top
layer leather price is 3-5 times the second layer of skin. Sports,
particularly basketball shoes use suede
