Yes. If this occurs when you are just standing around in them or skiing, you might be in a tight fit and that is not ideal as we all want to be comfortable when skiing.
If you flex forward in your boots and your toes come away that’s good, but it’s not going to help when you go over a bump or jump unexpectedly and jam your toe into the front of the shell.
A custom footbed can help by supporting your feet into a neutral position, and will shorten some people’s feet by 1cm. This will help to stop your natural pronation and your toes touching the shell.
