I don't know where you heard this from, but Crystal will remain open until there's no snow left to ride on, which was all the way until July 16th last year. The snow pack is deeper now than it was at the same time last season, so it's reasonable to expect at least until June, maybe longer so long as the temperatures don't stay too high during the spring.
Your only problem will be that those last couple weeks will only see Green Valley running, and that only serves hard blue/low black terrain. By the time that rolls around you should know whether you can handle those runs or not though.
Oh, I was just quoting the current operation schedule on their website. I know that they right TBD for June and July, and I believe they were open until June or July last year, but I didn't want to count on that in case they do close early.
Your toes most likely hurt because of the heel lift. When you're heel lifts your basically tip toeing that whole run if you're on the toe side.
Do you mean if my heel lifts within the boot, or just toeside in general? I think I have very little heel lift with my new boots. On steeper slopes I do make the mistake of trying to tiptoe to apply toeedge pressure rather than driving the knee towards the hill and letting the boot tongue take my weight.
