Adidas Galaxy 7 Shoes Deformed In Three Months - No Return

On May 26, 2016, I purchased the Adidas Galaxy 7 shoes from Boyner. My daughter used them three days a week for only one hour of running. However, within just three months, both shoes began to deform in the same areas. We sent them back to the Boyner store where we purchased them a month ago for inspection, but they confirmed there were no issues. I believe the deformation of the shoes in such a short time is a manufacturing defect. I request a return or exchange. My order number is 4155384231. I request that this issue be resolved as soon as possible.
