In Japan you take your shoes off at the door, so they gather in the genkan (entrance hall) and storing them is an everyday problem. Add the humid climate, and it is no surprise that people here share a great many tips for making shoes last.
| Item | Guide | Why |
|---|---|---|
| After wearing | Dry overnight somewhere well ventilated (do not put them straight into the shoe cabinet) | Feet are generally described as giving off about a cup of sweat (roughly 200 mL) a day |
| Rotation | Do not wear the same pair on consecutive days | The damp never fully leaves |
| Shoe cabinet | Dehumidifier packs (silica gel, etc.); open the doors regularly | Kept shut, humidity climbs above 70% |
| Long-term storage | Clean them, dry them, wrap in newspaper or non-woven fabric. Shoe trees keep the shape | Mould, loss of shape |
| Synthetic leather and trainer soles | Hydrolysis within a few years (it progresses even when unworn) | The nature of polyurethane |
[Verify] The sweat figure is a general physiology statement. Check the mould conditions in the Tokyo Metropolitan Government Bureau of Public Health material.
Cardboard absorbs moisture and releases it again. If you use the box, add a desiccant and open it regularly, or use a case with ventilation holes.
The opposite is true. The damp is trapped inside. A non-woven bag or a breathable cloth is the basic choice.
The polyurethane in the sole hydrolyses even when unworn. That is why trainers crumble a few years after being put away. Wearing them now and then, and storing them somewhere dry, can slow this down but cannot stop it.
Applying cream before wet leather has dried right through traps the moisture and causes mould. Only once fully dry, and thinly.
Deodorisers and dehumidifiers are different things. For damp, use silica gel or calcium-chloride types (除湿剤, joshitsuzai); for smells, activated charcoal and the like. Once the damp goes, the smell often lessens too.
