I bought the waterproof version of Alpinestars SMX 6 v2 boots and now wish I bought the vented version. My feet get hot even when it's only 70 degrees out. I am thinking about cutting out the waterproof flap inside the zipper opening and "venting" them myself. Has anyone tried "venting" boots by punching/cutting holes in the leather? If so, did it work? What did you use to cut the holes? I don't really want to ruin $300.00 boots but also don't really want to drop another $270 for a second vented pair.
