Incredible shoes - no sole bubbles when running hot, and super light. (order 3/4 size smaller)
So far, I've put about 12 miles on them, and no blisters or sore spots. They're sewn well on both shoes, and seem to fit about a 3/4 size larger than what I'm used to for Adidas running shoes. They're light, seem sturdy enough, and are definitely race-day shoes.I'm not a sub-4-h runner. I'll get there eventually probably. I can tell these shoes are a little advanced for me. They have pretty much no ankle support or pronation correction. In other words, they're not form-helper shoes. They're bowed up on the left and right of each sole, and are also sloped forward to back. The pivot point on the ball of my foot is lined up perfectly for toe-type steps. If you don't already have an amazing step, you may want to try something a little less advanced that will help you get there. I have fantastic balance and step, but I tend to run slow (often training under 25 miles per week). As a result, these shoes outrun me. I mean they are intended for a faster runner - so, I don't get everything out of them that are built into the price.Also, these are definitely street runners. If you're running on anything but sidewalk and street, you may want something with thicker tread. These are grippy but smooth on the bottom (like the difference between buying a street tire or a dirt-bike tire).Normally, in running shoes, I do about an 8 1/2. In Adidas running shoes (Terrex Ultra 240 (3 pair, etc) I wear an 8 mens. In these, I bought an 8, and they were half a size too big. The toe box is also the right width for me; but, have too high of a ceiling. I can lace them down super tight at the toe, and still have room above the front of my foot to flop around just about. In fact, the material actually bunches up on top when I tighten them down enough for my feet. A high ceiling on the toe box causes the pads of my feet to heat up more from friction earlier in my run. But, luckily, when it happens, I'm already running too fast for my breath to keep up - so, it serves as a nice notice to back off a tiny bit. Other people might not mind a higher ceiling on the toe box though. And it's not a deal breaker for me. I plan to wear new socks on race day, which will hopefully help with friction.So far, I really like these shoes, and am saving the rest of my miles on them for race day.A Relevant Note About The Brand and Quality Trends:Previous to these, I owned the black and white with pink stripe "Adidas Terrex Speed Ultra 240"s. I loved those so much. They were my all-time favorite shoe. I eagerly bought a second pair for my second year of training. There's a relevant reason I'm talking about other Adidas shoes. Those 240s had a flatter sole (less sloped to the front), great energy return, and were super comfortable. I quickly learned the shoe, and was running the best I ever had. No blisters or issues at all.I put about 500 miles on each pair. I literally wore them into the ground until my knees couldn't take any more - because I loved them and how they ran and fit so well. The soles wore perfectly even. I ran all over the mountains around Salt Lake and Provo, a few halves, and my first practice full in them. I was looking to replace them with yet a third pair of the same thing.The next year's 240 shoe I bought though (with orange on the front of the soles) had some significant quality-control issues. The heal was stitched weird on one foot. And the sole bubbled up on the same shoe weird when running on my toes. They messed up my feet so bad on my first two runs, I lost nearly an entire month of training: swollen ankle on one foot, bruised foot on the outside, and blisters on the other foot - all from two days of running/training. They were nothing like the previous model. Needless to say, I sent them back.As someone who has purchased and reviewed over 100 products on Amazon (nearly all from China), I find quality-control issues to be common among even high-end products manufactured in China. You may get a stellar-quality product or may be the unlucky person who gets something that will wreck your training schedule and put you in heal mode for a month - all the same brand and model. That's what happened with my third-year Terrex Speed Ultra 240 shoes.For trainers this year, I bought Boston 11s. One shoe bubbles up a little in the sole around the pad of my foot when I toe run - even in colder weather. The bubble gradually fades back into place as I slow down my pace and jog more flat-footed. It's sort of like that third pair of Terrex Speed Ultra 240s I owned - but worse because the soles are thicker and made from the same overly soft material. The other shoe of the pair of my Boston 11s gave me huge heal blisters I'm still recovering from. It bubbles up about three times greater than the other shoe from the same pair. And there's some crazy thing poking my pinky toe from underneath when I'm toe running. It's shaken my confidence in Adidas running shoes in general.In hind sight, I should have bought five pairs of those original white and black (with pink stripe). I'd still be wearing them. lol. But with newer Adidas shoes, I almost need to buy five pair just to find the issues with each shoe, and then match up the best left and right, and return or donate the others to a charity or something. It's been that bad lately. So, I don't know if I lucked out on the quality with these new adidas Adizero Adios Pro 2s or if the manufacturer puts more quality-control effort into them than some of their other shoes.My Adidas Adizero Adios Pro 2 shoes overall fit well, don't get bubbles, and seem to be sewn well. After the upcoming Salt Lake "This Is The Race" Marathon, if I still feel the same way, I'll probably buy another pair or two if I can get them for the same price - just because I'm worried subsequent models may not hold up to the reputation. Let me know if this longer-than-normal review helps you decide what you're going to buy.
