if my memory serves me correct It wish Jaspr1 would comment on how it is walking on snowshoes hunting snowshoe rabbits up in New England...I think he made comment once that you just don't slip them on and go... You got to be seasoned... I know of some kids once that wanted to walk the Appalachian trail... they started in Harrisburg and end up quitting somewhere in Hazelton.. see they purchased brand new boots and never broke them in... Ouch those dang blisters form real fast if your shoes aren't broken in...
Ya it be the crunch that alerts the critters... Not sure if there is anything that would take the Snap, Crackle, Pop away from walking on crusty snow... Truly again.... Me I have learned from many years of calling that it's just better to find the right property with the wind blowing in your face and hunt 25 yards from the road... They will come to you... You really don't have to go after them!!!! A screwdriver is a tool, a hammer is a tool, and the predator call is a tool...Use the tool to call them to you... Don't go after them...Not only do it when the snow is crusty... hunt like this all the time.. the deeper you walk in the more predators you will scare...
