Skechers Refused to Replace My D'LITES 4.0 Shoes After Inner Lining Tore Quickly

I bought D'LITES 4.0 model shoes from Skechers 7 months ago for myself and my wife. I only wore it on weekends and maybe 50 times in total, but the inner lining was torn and deformed immediately. Likewise, my wife's inner lining came off immediately and started to tear. I submitted my shoes for inspection and they refused, saying they were not defective. I leave photos of 2 shoes. I have previously used my Nike and Adidas shoes for 4.5 years without any deformation. It was the first time I bought Skechers and that was the last. I recommend those who want to buy this model, even from this brand, to think twice.
