If you're interested in buying football cleats here are some that are on sale for $39.99.  They are adidas, similar to the nike speed TDs ... pretty lightweight, about 10.5oz.  They have them as small as men's 6, but not in all colors.  Football cleats made for wide receivers are good for ultimate because they are made for cutting and sprinting, unlike soccer which are designed more for ball control.
