Hi, for anyone interested in the subject, FR and Powerslide plastics are heatmoldable in my experience. Rollerblade ones are not. I am a 297cm mondo but didn't want to buy 46-47 shell as it was too big. Instead I went for the 44-45 and punched the toe box with a reversible f-clamp and a custom wooden mold. Now I am skating something similar to a barefoot skate that fits perfect lengthwise and doesn't crunch my toes widthwise.

I will attach pictures of the process in a future post, but it's quite similar to what bootfitters do with ski boots.
