nike Safari Mercurial Vapor SuperflyIII Red/Golden bootsThe build quality of this shoe is very high, as these are the only vapors still made in Italy. Everything is well constructed and just feels really solidly built. The moving Sense stud is the concern of many, but I found it extremely solid and unlikely to break. The only concern for me would be the carbon fiber sole plate, but Nike seems to have improved it dramatically from when it first came out several years ago. These are shoes that you can safely buy to last you an entire season.nike Safari Mercurial Vapor SuperflyIII better than the Superfly II? The answer is yes, a little bit. Nike provided an extra lace hole at the top of the boot, which is the reason for the extra Flywire in the heel, a lower toe box and a shorter break-in period. So would I call this a whole new boot? No, this is more a Superfly 2.5 than a Superfly III. If you liked the Superfly II and are looking for some minor improvements, than it is worth the upgrade. You will get a supportive, tight fitting shoe as well as phenomenal traction. It definitely is better than the Vapors and if you have the extra money, it is worth going for the Superfly.
