I know I've said it before, but I'll say it again. I really enjoy Dane Burns' blog, Cold Thistle. If you like ice and alpine climbing, check it out. He has a lot of experience, good advice, good opinions (that I agree with about 98% of the time), great gear reviews and comparisons, etc.
Today I noticed a post of his about crampon fit, which reminded me of a different post of his that I'd read last year about fitting crampons. It's an important concept. Worst thing I can imagine is being half way up a route and have your crampon fall off. If you ever climb in crampons, check out this post, it's worth your time.
