Adidas Kids’ Shoes from Deichmann Worn Out in 2 Months – Quality Concerns

I bought Adidas shoes for my daughter from Deichmann in September, expecting durability from a trusted brand. Yet, in less than two months, the shoes look completely worn out, with noticeable tearing along the edges. I can't believe such damage happened so quickly, especially for a brand like Adidas. It’s a shame to pay a premium for this kind of quality. I’m considering taking them back to Deichmann, but I fear they’ll blame “user error.” How could a child cause such internal tears? It looks as if they were chewed through. Adidas, this is not the quality I trusted; I need a proper inspection and a fair resolution.
