And are the uppers made of leather because they didn't resemble any leather I'm used to.
It's the soles that are leather, thats what your walking on and what gives the comfort. There are some leather 'uppered' ones as well but they tend to be mostly shoes.
I love my Birki's but then I can't buy other brands as they don't fit. As a diabetic too it's important to look after your feet as best you can and I just know with Birks I am in safe hands. Just took delivery of my new summer pair today, gizehs but still have 4 different style pairs on the go that I wear for different tasks. For me I think theyr'e great and yet my first pair I hated, a year later I tried them again and they were heaven. Some are quick to be comfortable, some arn't.
I have a pair of traditional Crocs but I feel like a clown when I wear them and they do rub and also Mary Jane style, I love them but they have bruised my big toe so I can't wear them any more. So for comfort/love and my only choice, I'll stick to Birks.
