Hello, this is just a quick review for all those interested.
When I started doing parkour, I went out searching for the right kind of shoe to wear. I had read an article on MovNat, so I was looking for something that resembled barefoot. I also wanted something lightweight and durable with good traction. Because I had not been doing this for very long, I didn't know really what to look for in impact protection and all-about usefulness. After doing a whole bunch of research on the shoe I wanted, I came across these:
http://www.amazon.co.uk/Nike-Air-Rift-Mtr-Ii/dp/B0026MQPV8/ref=sr_1_1?ie=UTF8&s=apparel&qid=1249608918&sr=8-1And immediately set about buying them and running with them.
FITInitially, there were things that I had to do that were... unusual for me. You'll notice that these shoes are at the UK Amazon site. This is because Nike does not ship them out here in the US. In fact, Amazon was about the only reliable company I could find to ship these out here across the pond. That said, I had no way of testing them before buying, or for that matter sizing them. I had to measure my foot and estimate, hoping for the best. The shoes I ended up with were a little larger than I think they should have been, I think a half a size smaller would have been better but so be it. Because they are split-toe, I think having a tighter fit may be a grass-is-greener situation: I can imagine it would be better for functionality and transparency, but would probably create more toe-wedgies (more on that later). On occasion, if I clip my toe on something or land a cat leap a little off, my foot will slip out of the top of the shoe. I think this has more to due with the half-size off difference than the shoe itself.
3/5 (mostly due to my own guestimates)
FLEXIBILITYThe shoe itself is made out of a sort of tough jersey material, and the bottom of the shoe has two sort of 'channels' that separate the ball of the foot from everything else. If you land on a rail right on the ball of the foot, curling your toes around it is remarkably easy. It behaves like your barefoot would, no doubt. That said, there really is no give in the arch of the foot down to the heel. The first few runs took some getting used to, but I'm happy with them now that I've adapted.
5/5
WEIGHTObscenely lightweight. The shoe is mostly that jersey fabric and lycra, the only thing that weighs anything is the sole. Really, it's like wearing nothing at all.
5/5
GRIPDepends greatly on the surface. Some things it grips like glue (metal, bark, wood, gravel, concrete, rocks, carpet), other things it lags on (anything wet, especially wet granite, drywall, and painted brick... though it does really well on painted metal, for whatever reason). I haven't had any trouble with a lack of grip, really. I have had trouble with too much grip, but I'll get into that a little later. The waffle texture on the soles is beginning to wear down, but the grip isn't wearing down any.
5/5
BREATHABILITYThe Air Rift has an open top, and also allows some air to pass through the split-toe. There is fabric inside the split, but it's a light lycra and breathes well. They also have a heel strap, so there is open air passing through that hole also, though it's obviously less apparent. Since the MTR series is made of that heavy jersey, it breathes really well. Leather might be a little less airy.
5/5
CUSHIONINGAgain, this shoe is supposed to be like running in bare feet. Due to this, the cushioning is almost non-existent. But, that said, the arch is well supported. I also noticed that the shoe quickly picked up my foot contours and the stock padding became like a tough second skin.
1/5
DURABILITYAbout that. The shoe itself has held up quite well so far, and I've been using it consistently almost every day for the past 6 months. The tip of the shoe is starting to wear because of some failed wallruns, scraping the front fabric against concrete (or, in a few instances, grip tape). The split toe on the right shoe developed a hole at the crease that got larger - so much so that it worried me that it would split the entire shoe in half. I put some super glue on it and it's held up well, despite looking permanently stained. The leather models of the Rift might not be prone to these sorts of holes. The rubber on the bottom is starting to wear on the inside ball of the foot, but it has so much rubber that I doubt it'll matter much in the long run. All-in-all, I'd say these suckers will probably last a year of moderate use.
3/5
PRICEExpensive as hell, all things considered. After conversion to US dollars and shipping, the shoes alone were about $150. Then, because they are split-toe, I had to buy socks. The only socks I found around here were the Injinji toe socks, about $14 a pair. The socks are comfortable and unique, but not really worth $14 each. Also, I couldn't take the stock padding for distance drops, so I installed a sports insole. I think it ran about $20. Expensive shoes, definitely.
1/5
GENERAL COMMENTSToe wedgies. The socks I had to buy for these were made of a sort of nylon, but the padding on the inside of the shoe is designed for grip. Also, the rubber itself is designed for grip. Therefore, the socks have a habit of moving on their own accord inside the shoe. The wedgie gets annoying. I also had to install an extra insole for padding which worked OK until the blue fabric on the outside fell out. Underneath that was a sort of spongy rubbery padding that tends to stick to everything. It's bad for toe wedgie, but it's good for grip sake. All in all, I'm rather happy with the shoe, even through the mods and concessions I had to make.
BOTTOM LINEI wish they were more inexpensive, but I plan to hold on to this shoe until it utterly disintegrates. It is by far the most comfortable shoe I've ever worn, and I believe that running in something this close to barefoot has improved my technique significantly. If you're looking for an all-around trainer, seriously consider the Air Rift. It is a unique and quality shoe, remarkably well suited for parkour.
I hope this has been a good guide! Let me know if you have any specific questions.
