STACKABLE STORAGE: Each shoe storage organiser is corrugated and has tabs, which interlock when another box is stacked on top. This makes the boxes easy to stack and will stop them from falling over. Since the boxes are transparent, you can easily select your favourite pair of kicks to wear each day. Suitable for most shoes from heels, trainers, hiking boots, sports shoes, dress shoes, flip flops, sandals, loafers, boots, slippers and more. ABILITY FOR SHOES TO BREATHE: Each stackable shoe box features two holes, which allow your footwear to breathe. This will prevent mould and mildew from building up in and on your shoes. The durable plastic material is also waterproof so your shoes will always be kept in the best condition. Perfect for storing collectable sneakers so they remain fresh. TRAVEL CARRY HANDLE: All the clear shoe boxes feature a carry handle meaning you can easily transport your favourite pair of shoes. This makes it easy when taking your training shoes to the gym or if you need to transport your hiking boots without making a mess. Also since the shoe organiser space saver boxes can be flat-packed you can bring a couple of boxes in your suitcase when travelling.
