sport planet got.

usually discounted shoes are expired shoes. mind you, outsole can expire and harden.

usually for shoes over two years, it will start to degrade and that is when i would consider it expired. your sole will start to crack, disintegrate or hardened depending on how you store it.

that is why nike only provides 2 years warranty on their products.

"Nike does have a 2 year return policy for non wear-and-tear damage to their shoes. Look for the date on the right side of the size tab inside your shoe. The policy covers 2 years from that date.3 Apr 2023"

i remember someone from Malaysia did that claim with Nike store before.

if you notice, shoes on shelves ie JD sports, Footlocker, Nike or Adidas boutique, they don't display or sell their shoes more than 6 months and if they do, it will be discounted but most of the time especially boutique stores, they would rather dispose to smaller retails like sportsplanet/walmart/payless shops.

my airmax will never get to be worn over 4 years, soles will come apart, crack or disintegrate and this is the same for my over 20 pairs of airmaxes.
