How long can a new pair of sneakers be stored unused before its durability deteriorates?

How airtight will they be kept? Air will <slowly> degrade the rubber – but by “slowly” I mean several years. Ultimately the rubber will dry out and become brittle. Look at some old automobile tires to illustrate what I mean.

If the sneakers are kept in a relatively static and airtight environment, they’ll last much longer.

But in any event, you can count on multiple years.

^^Thanks so much! Just bought a pair of reasonably priced sneakers and shocked how soft and bouncy the cushioning is. Thinking of buying two more, seriously. lol

@mazingerz88 I was told by a shoe salesman years ago that buying two pairs at a time of shoes you find and rotating them preserves their cushioning much longer. I don’t always but sometimes do that or buy a second pair and forget it in the box for months. It’s still fine.

@mazingerz88 I normally get tennis shoes two pairs at a time, like @janbb wrote, and swap them from time to time for evenness of wear. I wear a 15–16 (mens) shoe – big feet – and when I can find something I like in my size, I load up.

Indefinitely if kept out of the sun.

In Florida? Shoes fall apart in Florida, they become unglued. Lol. Still, you usually get a good 8–10 years out of most. In states more north they usually last longer.

I’ve had a nice sneaker pair for probably 5 years, still pristine as special occasion gear.

Longer than you would think. 15–20 years if stored in the dark in a climate-controlled room.

^^Oh wow. Isn’t that something. Under the bed or in a closet in its box is best I can do I think.
