Totally agree. Since we know that the Sport Kit works with any brand of running shoes, the first consideration for anyone buying new shoes should be which ones are right for their running style, not brand. As stated above, the best advice is to go to a store that specializes in running shoes and have them give you a thorough evaluation. They'll measure your feet, watch you walk, etc. If they just ask for your size, that's a good sign that you're not in the right place.
People generally give up on running for two reasons, either they start off doing too much too soon, or they're not wearing the right shoes (or both). Either can lead to injury and frustration.
I'm not a Nike basher... they may be perfect for some people. Just remember, the coolest shoes may not be the best for
your feet.
