"Last season we had a very isolated issue with Heelcups. Those things are injected in Italy, shipped to Canada where they get Nano coated, then shipped to China for assembly. A huge pain in the butt. Basically what happened is during "step 1" of injection whoever was running the injection machine that morning didn't allow the tooling to heat up long enough. Keep in mind that we only make about 400 pairs of these. I think we estimated that 20-25 of them were faulty, which all ended up in the US. So that 25 or so pair all happened within about a 5 minute span. That's how precise things need to be."
