As you can see… I have spent a lot of time in these. I have a particularly close relationship with them actually. They have been very good to me. this is the first pair of size 11′s made… they are 18 years old now. They squeak like tortured weasels when you skirp them on the floor. Something to do with the rubber compound… heh heh. We’ve sold several million pair since these… I am nothing but thankful for all this.
