What brand of shoes is Aldo wearing?

I love the fresh modern styles in this film. Although this was over 30 years ago, Lovelock's skate shoes, long blond hair, cuffed jeans, and freshly laundered white dress shirt would work just as well today. (Although we could do without the gap in the front of his teeth.) My question is this: What brand of shoes is he wearing? They are blue denim with Kedds-style soles and a little cuff around the back. The logo is two interlocking squares. I have checked Eastbay's entire selection, but am sort of at a loss, here. Again, this was over 30 years ago and the brand may very well no longer exist. Thanks.
