A way to attach the outsole and midsole to the upper body using “cement”, or more commonly: glue. Cemented shoes be found in all price ranges for most footwear types.
A highly renowned construction method considered to be one of the best for shoes constructed with a welt. A method for stitching outsole to welt and then the welt to outsole. Due to this two level stiching resoling is relatively easy to conduct.
Vulcanization is the process for transforming natural rubber into a cured, more durable rubber. It will become less sticky and since the rubber normally melts slightly in the controlled vulcanization process, making it bond with surrounding materials. One of the most common processes to make footwear.

There are several different kind of TPEs, thermoplastic elastomers, also known as TPR, thermoplastic rubber. The most common in outsole production is SBS, Styrene-butadiene-styrene, SEBS, Styrene-Ethylene/Butylene-Styrene and TPU, thermoplastic polyurethan. Normally when TPR is mentioned it refers to SBS. TPU is widely known under it´s correct name. EVA is also a thermoplastic elastomer but is handled in a separate article.
