OK folks, I need to ask for some advice on something. I am intersted in snowshoeing to supplement the x-c skiing. I however, don't know anyone that is "into" the recreation to get a good answer. I have been looking on line and in catalogs at different shoes. I have noticed that there are 2 styles. One that is a "V' shape and the other more like a "U" shape at the backside of the shoe. What is the advantage of either shape/style. Is one supposed to be better than than the other? I've asked for some info at a sporting dept. store but they only sell men's shoes, which they state are 'unisex".. and were trying to sell their item as it works for everybody. I have read that womens are more narrower and a little lighter than the men's as to why I wasn't buying the speel about unisex shoes. Or are they right? Any pointers, advice, reccomendations you could give me, it will be greatly appreciated. Thanks..
