The sporty Invisible for cold days: thanks to climate-regulating, warming merino wool and a padded plush sole, the Invisible are the perfect companion for sneaker outfits during winter. Due to the particularly high cuff and a special heel construction, this style is completely without silicone and still offers optimum grip in the shoe. The anatomical FALKE fit with a knitted "L" and "R" convinces with a perfect and comfortable fit.
