Snow shoes?

We've always wondered why humans can't walk or run through the snow as well as we can?  You humans have no problem opening doors or containers, so why do you slip and slide around so much when there is a little snow on the ground???  We have a few ideas for an invention that will allow humans to move as easily through snow as we do, so if you know of any way that we can get this invention moving forward, please let us know.  In the meantime, if you see us out during our daily walk or run and our owner is slipping and sliding on the sidewalk, don't laugh at him....it's not his fault he doesn't have the moves we do.
