Under Armour Sneakers Repeatedly Fall Apart Inside Within Months

I've purchased athletic shoes from Under Armour several times before. While the shoes are generally comfortable, I've run into the same problem with all of them. The fabric and padding on the inside of the shoes start falling apart very quickly, the inner lining tears, and the shoe both ends up looking really ugly and becomes unusable after a while.
With the most recent pair of athletic shoes I bought, the same problem showed up in less than 2–3 months. Because of the tearing and deterioration on the inside, I believe the durability of this product absolutely fails to meet what you'd expect from a brand at this price point. I had bought the shoes from the Armada and Kentpark stores in Ankara. Since I knew there was no warranty and didn't think an exchange would be granted, I just kept using them until they were done for and never filed any kind of claim.
My purpose in writing this complaint isn't so much to make a request of Under Armour, but rather to inform other users considering buying athletic shoes from this brand about the durability of the inner padding and fabric components. I especially want to point out that experiencing this kind of deterioration in such a short time doesn't match up with the brand's supposed quality.
