PU consists of long polymer chains that are gradually split apart due to the effect of moisture. As a consequence, PU loses flexibility over time and gradually becomes brittle. As the shoes reach an advanced age, this can lead to signs of disintegration in the soles.
Hydrolysis is the chemical breakdown of the PU polymer and the resulting physical breakdown or crumbling of the PU sole by the attack of water (usually in vapour form), occurring over a period of several years (even when the shoes are in store!). This process is accelerated by warmth and high humidity.
Most shoes are made with a rubber outsole, which grips pavement and adds durability, and a foam midsole to absorb shock and provide a springy feel. Sadly, neither component lasts forever; both will eventually break down, even on unworn shoes.
Cheap soles tend to wear out fast. It is also a good idea to get more pairs of shoes, so you don't overuse a single pair and cause premature wear and tear. Stuff your leather shoes with a newspaper or a wooden shoe tree to prevent creasing and allow the leather to breathe.
Linings wear due to a combination of friction and moisture which causes the inner surface to tear and disintegrate. The back portion of the lining which makes contact with the heel is most susceptible to this wearing process.
Should you choose to go with a plastic shoe tree, make sure to place a few silica gel packs in the shoes to absorb excess moisture. If you can't get a hold of a shoe tree, try stuffing your shoes with acid-free paper — it will help the shoe retain its shape while absorbing some moisture.
Apply a thin layer of shoe repair glue adhesive to one surface. For example, if you want to fix a flapping sole, apply the shoe glue to the bottom half. Now press the torn parts together. Make sure to do this quickly after applying the shoe adhesive for maximum effect.
The synthetic materials in modern sneakers will begin to crumble into dust whether or not they are ever worn, even if they are kept in their boxes in a cool dark place. After five to ten years the midsole foams will get hard and the cushioning will deteriorate noticeably.
Keeping your shoes stored in a cardboard shoebox for long periods can make them absorb any moisture that builds over time. Moisture causes the shoe to crack, making it difficult, if not impossible, to restore. It also causes discoloration, making the shoes look older or dingier than they should be.
According to podiatrists, everyday shoes need to be replaced every 8 to 12 months – or when they start showing signs of wear and tear.
Compared to piling all your pairs on the entryway steps, having them stored inside their boxes is a better idea since shoe boxes are easy to stack and identify. Cardboard boxes can resist a small amount of moisture. This can protect your shoes from the damage caused by humidity.
“A $180 pair of shoes will last you twice as long as a $90 pair of shoes, but a $360 pair of shoes can last you a lifetime”. What's missing in that statement is in order to make that $360 pair of shoes truly last a lifetime, you need to take good care of them. Here's some advice on making them last (get it?).
The term hydrolysis refers to the chemical breakdown of the polymer used when making shoes with Polyurethane soles and occurs over several years, resulting in soles 'disintegrating' when stored in certain conditions for long periods of time.
Keep shoes in a climate controlled environment.
Climate-controlled storage is ideal for shoes as temperature and humidity extremes turn leather brittle, weaken fabrics and cause glues to loosen. Shoes left too long in attics or basements can become unusable within a season or two of harsh treatment.
It's important to keep cardboard boxes dry and free of pests to extend their lifespan. If you need to store shoes for an extended period of time, only use plastic containers. If you don't plan on wearing a pair of shoes for at least a month, it's best to store them in a box.
PU consists of long polymer chains that are gradually split apart due to the effect of moisture. As a consequence, PU loses flexibility over time and gradually becomes brittle. As the shoes reach an advanced age, this can lead to signs of disintegration in the soles.
If you keep a pair of sneakers deadstock in their box for too long, the glue will dry up and the aging process of the shoe actually accelerates when compared to a shoe that has been worn every once in a while.
DS stands for "Deadstock" and refers to shoes that have never been used or worn but may be from a previous season or model. It's a popular term in the sneaker world and highly coveted by collectors and enthusiasts.
On average, shoes can last from two to seven years depending on the quality and the way they are cared for. Many people wonder how long their sneakers or flats will last. If you are actively using these shoes, you'll have to invest in a new pair faster than a pair that's worn for fashion.
After five to ten years the midsole foams will get hard and the cushioning will deteriorate noticeably. After 20 - 25 years (and possibly sooner) they will literally be unwearable.

If we are talking welted shoes, you can expect anywhere from 2-20 years from them, assuming you take decent care of them. If you take exceptional care of them you could have them +20 years.
We define ample time as around 24 hours – so ideally give it a day between wears. If you don't give your shoes a day to air out, the sweat-soaked leather will warp, and your shoes can start to lose their shape — not to mention get musty and start to smell.
The synthetic materials in modern sneakers will begin to crumble into dust whether or not they are ever worn, even if they are kept in their boxes in a cool dark place. After five to ten years the midsole foams will get hard and the cushioning will deteriorate noticeably.
The traditional rule of elegant dressing recommended seven pairs of shoes, that is, as many pairs as there are days of the week.
