Reebok Shoes' Inner Foam Fell Apart After Only 3 Months of Use

I bought a pair of Reebok shoes, used them carefully, and they seemed great at first. I took good care of them, but after just three months of light use, both sides' inner foam completely disintegrated. When I bought them, the salesperson praised their quality and durability, so I didn’t hesitate to pay the higher price for a trusted brand. Now, I’m left disappointed. The exterior is still in perfect condition, showing how carefully I’ve used them, but the foam inside is falling apart. This shouldn’t happen to a shoe from a brand like Reebok. It’s not an issue that needs investigation; it’s clearly a manufacturing flaw. I hope Reebok addresses this problem quickly.
