We recommend using shoe trees to extend the life of your shoes. Cedar is used for a myriad of reasons. It is a natural and solid wood with a pleasant scent that absorbs moisture, being renowned for its anti mould properties. Quality welted shoes should last up to 10-15 years with the proper care and maintenance. Di Bianco recommend that new shoes only be worn for 2-3 hours until broken in and comfortable. Shoes should not be worn two days in a row, allowing for a period of 24 hours 'rest' in between. To ensure the quality and shape of your shoes, shoe trees should be inserted after they are removed. If your shoes get excessively wet, the shoe trees should be inserted immediately, with the shoes laid on their sides and left away from direct heat (fire or radiator etc) for 24 hours. Please note - it is suggested you order the shoe tree in a size below that of your shoe.
