The Slim High Arch Flex Orthotic from Icebug.

Icebug Insoles SLIM is an extra thin version of our insoles. Slim fits perfectly in shoes adapted for, for example, running and football, but also in everyday trainers. The Slim soles provide as much support as the Fat soles but a little less cushioning. The soles are 2 mm thick and available in three variants: Low, Medium and High, which are adapted to different types of arches.
