Icebug Insoles SLIM is an extra thin version of our insoles. Slim is perfect for shoes that are adapted for, for example, running and football, but also for your everyday sneakers. The slim soles provide as much support as the Fat soles but come with a little less cushioning. The soles are 2 mm high and are available in three different versions; Low, Medium and High, which are adapted to different types of arches.
