Birkenstock Mayari Model # 540-362

I had to write to left you know how unhappy I am with this shoe. I purchased them in May 2022, which I know is a long tine ago, but I was saving them for a vacation I went on July 2023. When I started to wear them I tried them a short time a day to break them in as them say. I had such a painful time as the foot bed is as hard as a rock shooting pain up my leg every time I would put my heel down on the foot bed. I have stopped trying to to wear them in the house for short times as the pain is too much and after two weeks is still there. I am so unhappy with them and can’t understand how they can say they are so comfortable. Maybe you can get back with me if I should write the company.
