You need the lightning accent------------I would also recommend the Lightning Ascent based on the more durable materials, three straps on the fore foot rather than two for more stability, more aggressive frame traction, and the famous climbing bar which allows more of the muscles in your legs to climb up steep terrain. As far as the size goes, I try to get away with the smallest snowshoe I can. The reasons being a smaller snowshoe is lighter, easier to maneuver in, less likely to be stepped on, easier to get up if I fall, less effort dragging them through the snow, etc. I would, therefore, recommend the MSR Lightning Ascent 25s for you. However, if you find yourself in deep snow often and you don't mind a bigger shoe, the 30 inchers might be a better option. They will give you slightly more loft (meaning keep you more on top of the snow) and the Lightning Ascent series snowshoes are the same width throughout the line meaning that they are all pretty easy to get around in (some snowshoes increase their width the larger they get making it more difficult to walk). Both sizes will accommodate men's feet up to size 15.To balance your advice here, when hiking trailless and trail breaking, you should go with the biggest snowshoe you can handle, not the smallest. Smallest is for broken trail and very firm conditions only. The definition of snowshoeing seems to be forgotten after high tech snowshoeing came along. There is still only one way to stay up on soft snow and that is to use a large snowshoe. Unfortunately, the manufacturers make very few large snowshoes. I really don't know why customers don't demand bigger ones myself.
