The BOA® lacing system is an innovative closure system that makes it easier to put on and take off shoes and boots. With this fastening system, a single stainless steel wire is evenly tensioned via a turning wheel and released again by briefly pulling the turning wheel. This makes it quick and easy to optimally adjust the shoe to the individual conditions of the foot. Thus, a secure and comfortable fit can be achieved with a single movement. At welly-king.co.uk you will find the BOA® closure system on shoes and boots from the Viking collection.
