I have a pair of Redfeather Racing Snowshoes. They're similar to the Sport Model but have a number of more well built and durable parts. I believe the Sport is actually discontinued at this point, but I imagine they are available at pretty good discounts at various places. I woud say the Sports would be good for medium duty use, not for serious hard hiking and climbing. I don't think they'll hold up or perform in more intense climbing situations. Plus, neither the Sports or the Racing models are good for breaking trail in deep powder. All that being said, I love my Race shoes and find I use them about 75% of the time. They have a great binding, titanium crampons that really work and are strong, and the pointed tails are great on the downhills, they kind of act like a rudder. (I have a pair of MSR Denali EVO Ascents with optional tails for more serious conditions. These shoes, by the way, are terrific, and the choice of many other users of this web site).
So, ask any more specific questions and I'll be happy to respond.
