To make your sneakers last longer, spray them with a good repellent to keep dirt and water from ruining them and repeat this every two months. Try using a sneaker care kit, which includes brushes and cleaners meant specially for them.
Clean the laces by soaking them in a bowl of water mixed with laundry detergent or the sneaker cleaner. Get rid of the insole odour using a natural deodorising spray and try storing your sneakers in dust bags or their original boxes. Rotate your pairs and don’t wear them for more than two days in a row.
