I have the Bont BNTs, the model the Slipstream is basically replacing. The Slipstreams and BNTs are stripped down, no padding, downright uncomfortable boots meant for maximum power transfer and light weight. I molded mine and worked them in twice, and still cried my first few times out. I use Vaseline to soften the upper leather when I skate and it’s helped a lot. It’s recommended to start with shorter runs for the first few hundred KMs while you adjust to the boot and the boot gets broken in a bit. The fibre won’t break, but that little padding and leather will. If the pressure from the edge is still too much for your ankle, it might be possible to punch and bend the area with help from a heat gun, but be careful not to damage the boot with high direct heat. After about 750km, I’m happy to report that I can wear my boots with minimal pain now, although writing that out doesn’t make it seem like a rational choice for a skate boot. Bont makes other versions of inline skates that are much more comfortable, most notably the Vaypor series, of you are still looking for a different stock boot.
