Looking for Answers about Nike MayFly - Men's?

The men's Nike MayFly is a minimalistic shoe that uses the least amount of material possible in the construction. Two reasons...keep the weight down and also the price. The distance you use the shoe for is entirely up to you and your comfort level. I have some runners who will use this shoe until it shreds...literally. The shoe should last for most at least 60 miles, which is still about 97000 meters. So a person could get in quite a few 3000m runs.

Actually, although in the end it is your personal preference whether to race these shoes for shorter distances, the men's Nike MayFly spike is considered a "racing flat", which is a lightweight athletic shoe designed for long distance track & field, cross country, and most often, road races. The flats differ from regular spikes for a few reasons: they lack a substantial heel, they have no holes for metal pins in the shoe, and flats do not have a particularly aggressive tread. The idea of making the racer with minimalistic materials benefits the runner with a very lightweight shoe. Thus the reason they are more designed for long distance racing. You can do a simple search on the website by using keywords "Sprint Spikes". This will offer you better choices for a shoe made for distances of 100-400m.
