If you are looking for occupational footwear with a comfortable, light and flexible sole, I recommend a pair of Safety shoes with PU soles, outsoles made out of polyurethane.
Polyurethane is nowadays the most used material in the world of safety footwear, referring to which often the abbreviation “PU” is used.
It’s necessary to distinguish between PU soles (single-density) and PU/PU (double-density)
SINGLE-DENSITY PU: it’s a very light material which guarantees high levels of comfort. It has good resistance to chemicals and hydrocarbon, but no resistance to strong acids. The temperature tolerance lies between -10/-20 and +130/140 degree. The softness of the material gives the sole a good ground adhesion, so that its slip resistance is comparable to that of TPU and rubber.
RECOMMENDED USE: indoors or in non-extreme work environments
PU/PU: the sole consists of two layers of PU with different densities. It has good resistance to chemicals and hydrocarbon, but no resistance to strong acids. The temperature tolerance lies between -10/-20 and +120/150 degree. The soft PU midsole guarantees good shock absorption and comfort.
RECOMMENDED USE: indoors and outdoors, not recommended where there is a chemical risk.
