My Air Zoom Vomero + 2s performed fine on first wear. My arches were the problem. I tweaked an arch during the first run in my Vomero's. My previous shoe was an Air Max 360. (I used the 360s for like 13 months, an amazing time span.) Actually, I think the 360s made my back ache. I believe they had a little too much support. Plus they were rather stiff. Nevertheless, the AM 360 is an engineering marvel. Every serious runner should try a pair. The 360s are great for heavy milage, and the cushioning is unquestionable.
Natually, my feet were acclimated to the AM 360s when I made the switch to the Nike Plus compatible Vomero + 2s. The AM 360 is not compatible with Nike Plus. This fact prompted my conversion to the Vomero.
The Zoom Vomero + 2 is the best running shoe I have ever used, and I have ran in Nike Zoom Milers and the 360s. Some runners have posted complaints on the Internet, saying the Vomero is too mushy. These are probably the same folks who require a stability shoe to stabilize their gait. I have a neutral gait, so the Vomero suits me. Stability shoes wreck my lower back because they do what they are designed to do, limit pronation. My feet and ankles must pronate. If they don't, my back feels it. I can feel the pressure on my back after fifteen minutes in a stability shoe whether I'm on my feet or off.
The Vomero + 2 has the right support in all of the right areas. The shoe is flexible, responsive, ventilated and well-cushioned. Save for the first few wears when my arches were too weak to handle the Vomero's awesome Free-inspired flexibilty, I haven't had any problems out them. They've been a dream to run in. Unfortunately, my Vomeros are into their fifth month of use. The time is nigh for a new running shoe. Perhaps I should just stick to my Hyperdunks throughout the rest of 2008. They have the ability to get the job done. Plus they have Lunarfoam in the forefoot!
