The state of the modern snowshoe is a mystery to me. All I can figure is they are for groomed trails...most of them are ridiculously small for all but the hardest snow conditions. But there are good ones out there...just not in REI for the most part.
I've used several different snowshoes over the years, traditional and modern. The pair I settled on are the Northern Lites Tundra. Lots of flotation and
very good grip on crusty, icy snow, too. I have size 15's, and the bindings fit fine. They're the lightest, toughest, best floating synthetic snowshoe I've found to date.
24.5 ounces per shoe
http://northernlites.com/tundra/The best floatation I've ever had in powder was with 60" traditional shoes, and if stamping out a runway in deep powder is your mission, they're your shoes. But they suck on steep hills or brushy country or in crusty, icy conditions.
Traditional snowshoes also take a fair amount of upkeep. The varnish will last a whole season if you don't walk in anything but powder, but all it takes is a half hour on crust or ice and the varnish needs to be reapplied. Not a huge job, but not worth doing day after day when there are better alternatives.
Without the varnish the wood and rawhide is vulnerable to moisture. It takes very little moisture to swell the wooden joints or turn the rawhide to mush...conditions which are aggravated by refreezing them, and a pair of snowshoes that should last three lifetimes can be ruined in a month. That's one reason you see snowshoes hanging
outside the cabin...it was disadvantageous to let them thaw out. If you're putting them in a warm airplane you'll have issues if you don't care for them.
Synthetic snowshoes eliminate that problem, and properly designed they will give more floatation for the same footprint because the decking is solid, not meshed. They're also much tougher (if properly built, and not all are), and most importantly, they give vastly superior traction on crust and ice. That's not a big deal on flatland, but it can be a HUGE deal when the terrain gets steep.
This sort of grip can literally be a lifesaver in steep country with hard snow.

Compared to everything else about flying, much less ski flying, snowshoes are ridiculously inexpensive. Pretty sure there's no law against having more than one pair...
