Very good looking shoes
Size: 11, Color: Black/Black
I really like the way these shoes look. They look different yet “well known”, as in, these are regular flat shoes but with a very unique design that make them seem neat and “basic” yet different and stylish. I personally loved them. However, I don’t really understand how so many reviews call these “comfortable”. They are very well made, yes. These definitely promise to last. On the other hand; the fabric feels rather sturdy or rigid. They fit perfectly. For me personally, I have rather narrow feet and these may feel a tad loose, which does not help at all. My feet feel sore after walking on them for some hours and also they feel rather heavy too? I mean, these shoes are inexplicably heavy. Either way 10/10 in style 6/10 comfort
