It seems they need to sell as many trainers as possible and are not happy that we keep stock at home. They have resorted to trashing this idea by saying they have a sell by date so we have the chuck these ones and buy again. Stupid or what?
Does anyone know if there is a shelf life for trainers when they haven't even been used?
I was told today by a shop sales person that trainers need to be changed every 2 years even if you haven't run in them.
I was confused because who knows how long the shop has had them in their stock room and then how long did the manufacturer have them before they were sent to the shop. Maybe they should have a sell by date on the box ?
I have heard that the EVA in the shoes can degrade over time but that needs heat which is why I never dry my trainers near radiators or wash them in a washing machine.
Can anyone give me a good reason why trainers would degrade over time if they were left unused in a cupboard?
