I love my tubbs. I was deciding between these and the MSR Lightning Ascents (another fine snowshoe), but I'm glad I ended up with the Tubbs. My wife liked mine so much she ordered the same pair (in women's) and loves hers too. Exceptional traction in all terrain. I'm 5'6 170 lbs and the large is just the right size. They are a lot easier to walk in than other snowshoes I have tried. The flexible base plate really allows it to contour to the terrain, and the teeth underneath are massive. In other shoes, where I would slip on ice and hardpack, these gripped extremely well.
I'm not crazy about the bindings, but they work. My boots are a bit small for them, but they get the job done.
If you were going to be snowshoeing in waist-deep powder all the time, I might recommend some MSR's with long tails for floating. In every other condition, I couldn't imagine anything being better than these FlexAlps. Super lightweight, and they don't make you walk like a duck. I don't end up banging my snowshoes into each other all the time, and my gait is very similar to my hiking gait. Love 'em.
If you're worried about the price, I haven't tried them, but the cheaper version of these snowshoes look fantastic as well for the price (with slightly less spikey traction underneath).
