Hope this helps
1. the liners(before being heat molded) should feel very small and tight. Your toe should reach where the liner meets the sole all the way at the front. When they get molded the toe area will be larger because you'll wear a neoprene thing at the tip of your toes to create more space. The boots might seem uncomfortable but remember they're supposed to be snug and mold to your feet.
2. GET BOOT FITTED FOR FULL TILTS BEFORE BUYING. there is a chance that you had been fitted for a more recreational type of boot that gives your feet much more room. That's the type of boot your grandma would wear, but if you ski aggressively, please consider smaller sizes. You will get LESS shin bang if your boots fit more snug/are smaller(to a degree of course)
3. liners can be re molded
4. SPK=/=Full tilt. they're VERY different boots. if you have a wide foot dont buy full tilts or the "wide foot" full tilts
5. The Das Booter is the worst boot you can buy. If you do have wide feet, please don't buy the Das booters. they are not made to handle the performance level of the athletes who use them.
6. you can put the liners into other some boots, but not all. check to see if the liner fits in another type of boot if you have a wide foot/don't like the full tilt fit
7. You can always seek a real boot fitter that carries full tilts.
please feel free to contribute with other knowledge about these boots like different parts, etc.
