Hello, I have tried to search for your problem solution but can't find it. I will ask my friend regarding your problem solution because he is a website designer. But when I was searching for your problem solution online, I found https://brunomarcshoes.com/collections/loafers website where I found a lot of collections for loafers and I was so happy when I found that website. Because I want to buy loafer shoes but can't find the website from which I can buy them at an affordable price.
