Scented Bosanova Insoles: Universal insoles for any type of footwear. Most are multi-size and adjustable to fit each foot. The perimeter of the insole must be trimmed by the indicated marks, until the desired measurement is achieved. The most recurrent uses of an insole for footwear are: to renew the worn insole, provide greater comfort when walking, avoid unpleasant odors, and reduce the size of a shoe that is large. Materials such as foams of different densities or gel, are usually the most employed. The placement of the Bosanova insoles is simple and fast, being able to remove the previous insole from the footwear or incorporating it directly on top of the original one.
