The P25 snowshoe
The company most responsible for this change, particularly in terms of developing a performance-oriented snowshoe, is Redfeather. And they're still happily making snowshoes that are light and fast. An example: The P25, what they call a "performance" shoe, meaning it's light (3.5 pounds per pair) and fast, but has enough heft to withstand some abuse. Price is $219 (www.redfeather.com).
Of course, other snowshoe makers jumped in with similar light, fast models once they saw the niche Redfeather had started to carve out for itself about a decade ago. The Atlas Dual-Tracs ($239; www.atlassnowshoe.com), for instance, are under three pounds per pair, and have a low profile so you don't trip over yourself. Or there's the Dion Model 130 ($201; www.dionsnowshoes.com), a superlight shoe made by a small Vermont-based company.
Racing snowshoes are sort of like running shoeschances are, you'll end up with one pair for training (a little heavier-duty, maybe better float) and one for race day. So you might want a midweight shoe for training and general trekking. Then, for your races, something like Redfeather's F25 ($229), which uses titanium crampons and other features to pare down the weight to 2.5 pounds.
Have a great winter!
