If you feel just as comfortable running on top snow as you do running on top the sidewalk, then you'll need a pair of snow shoes, which will enable you to do the next best thing to walking on water. There are a number of manufacturers out there that provide snow shoes, so you'll at least have some selection when it comes to making a purchase.
When it comes to buying a great pair of snow shoes, you want to consider floatation, which refers to your being able to run on top of the snow as opposed to through the snow. Different brands will provide different levels of floatation. And while no brand will provide 100 percent floatation, the best brands will at least provide sufficient floatation, particularly if they were designed for professional runners who need to be able to stay on top of the snow as much as possible.
Also be sure to consider your weight because your weight will determine which pair of snow shoes is the pair for you. For instance, some brands are good for people 190 lbs or under. Other brands have different stipulations. So you'll have to keep this in mind before you make a purchase. You'll also want to be mindful of traction. Not all snow shoes provide equal levels of traction so finding a pair that does provide adequate traction will require asking the right questions.
Snow shoes also perform differently on ice, so the best bet for you would be to consult online sites that actually compare and contrast snow shoes. You might be surprised by what you find. Also be sure to consider factors such as whether the snow shoes are likely to fall off in different weather conditions or in different situations.
