There is a thread on boot fitting and why do my feet hurt. They could be too small or too big. My big toes use to get jammed forward into the front of my ski boots if I leaned back or didn't flex my ankles. Do your toes hurt when you just wear your boot, do they hurt when you are riding a certain way? ......
My boots fit me well. I can run and jump in them comfortably. I am sure the boots in my case is not the issue of getting a blue toe.
I was actually thinking about this thread when riding and teaching tonight. For anything less than some very aggressive carving or doing much toeside traversing on steep terrain, I use about 50-50 toes and balls of feet. I only really shift fully on the toes in those deep carves. The blue nail is something that happens slowly over a season with me. Every year I get this and it starts showing up around this time of year as a small area then gets bigger. I think my boot size is contributing factor as well as they are pretty tight.
Unless you are doing something extreme, I think you may in fact be using the toes when you should be using the balls of the feet. Maybe in your toeside turns, you are standing on the tip toes insead of driving the shins forward into the tongue of your boots. Try pushing the keens out in front of you more and flexing down. You should feel like you are "resting" your shins on the tops of the boots and taking some of the weight off. Maybe this idea will help you tweak your technique so you are not stressing the toes so much.
Thanks for contemplating on the thread while you were out there the other night. I really appreciate that. At least that makes me feel I did not bring up an irrelevant topic. I have read your post carefully and I think I understand your suggestion. Your suggestion does make sense.
By you saying 50-50, I get the picture that we could roughly exert more or less equal pressure on both toes and also balls of the feet, if we are not carving steep angles. Yes even as I told myself to pressure on the balls, I was aware that the pulps of my toes were not suspended above the insole of the boots. The toes were working too.
I think unless sport scientists put pressure sensors with transducers under the toes and also the balls of the feet to obtain some substantial data while we snowboard, or else we could only make estimates how much we are pressuring various parts of the feet at any given instances.
But Snowolf, thanks for your further thoughts and useful suggestion on the issue. Had you said 56-44 or 63-37, I would have gone nuts in over-analyzing how you came up with those apparently precise numbers haha.
