Shoes have their own odour once produced due to the various materials from which the shoe is made, and is particularly noticeable when these materials come into contact with adhesives. When stored in a shoebox for long periods of time, the odour of the shoes becomes stronger, but normally goes away after a day or two out of the box.
At uvex, we make sure - right from the selection of the materials - that our safety shoes are produced to be as odour-neutral as possible. We specifically avoid the unnecessary use of adhesives, keeping this to the absolute minimum. For many of our work shoes, our direct soling process allows us to completely do away with the need for adhesive when attaching the outsole. During production, the polyurethane outsole is foamed directly onto the outer shoe material - making uvex safety shoes largley odourless.
