"most of The shoes on the winter shoes are not designed for snow and ice tests show that winter boots are quite poor out of the halksynpunkt, according to researchers."
"Ishala streets, with snow and sleet about every other – we have several months in front of us then we are liable to slip, and make us ill. But it is not just a question of snow removal, what you have on your feet is also of great importance."
"The most common winter boots is really bad out of the halksynpunkt," says Viveca Wallqvist, researchers in different areas, including materials science at the research institute the Rise."
" We have investigated common winter boots available on the market, and looked at what the soles are made of. We looked first at what people really have on during the winter, we examined the in Luleå. So we picked up those shoes and tested them."
"the Result was disappointing," she says. Many of the shoes that people wore was not even designed for winter use, as the popular sneakers and nice boots with smooth soles. Also fixed the soles on the boots and shoes which have been sold as hearty vinterdoningar were bad. The rubber was just too hard in the cold, and the patterning was not sufficient for icy roadways."
"– the Soles were really not very good in the tests. Even if the shoes are vinterfodrade so it is not a guarantee that the soles are not slippery."
"the shoe soles are a separate industry within the footwear business," she says, and there are only a limited number of manufacturers in the world. It makes the same kind of soles can sit in the shoes of a different brand."
"She tells of an ambitious test undertaken in the winter land Canada. Hundreds of shoes were tested, where for the slip, but only a handful reached up to the beginning of the ten-point rating scale."
"– Just the shoes that were tested, which may not be available here, but it looks the same out here."
"the Patterning is important, she explains, it shall be a proper pattern with depth in the direction of movement, and preferably also at an angle to it."
"– It is also important with a large and good greppyta, so that the sole makes contact with the surface."
"Many soles had an admixture of dark material to make them resistant to UV radiation," she says."
"– It makes them more durable. There we saw that it is very carbon black, or carbon, is used. But coal is friktionshämmande, so it makes the soles extra slippery."
"Difficult for consumers"
"Now, scientists will hit the footwear business to talk about the results, and also discuss a scheme for labelling of footwear from halksynpunkt."
"– It would really be needed. It is very difficult for consumers to know how the shoes are in the winter. To the soles feel soft in the store does not mean that they retain the softness of the snow and ice, " says Viveca Wallqvist.."
"Shoes for winter should have a sole that does not become hard in the cold, then the grip worse. Patterns should be greatly in the direction of movement, and preferably also at an angle to it."
"Dobbar that is put on the outside of the shoe can work well, but the material properties of the metal and the rubber may vary."
"There are also loose metalic studs to screw in which the thick soles."
"There are some shoe manufacturers who are working in particular with the right to prevent slipping, for example with the built-in dobbar that sinks into the sole, and with particular soft rubber. There are also shoes with the involvement of various particles in the sole, which gives a sandpapperliknande syta."
