I am very familiar with the Nike Air Max running shoes, they having been the only athletic shoes I've worn for the last 20 years or so.  It's obvious that these shoes were designed to emulate the Air Max line.  I had high hopes for the ONE MIX but unfortunately, I couldn't really give them an extensive test as they were at least a half size too small in 12.5 which is the largest size they make at this time.  What I noticed when I tried them on and walked around the house is that they seem under-pressurized compared to the Nike Air Max so not nearly as supportive as Air Max even with upgraded insoles.  Also, they have a limited factory warranty at only 6 months.

With a larger size (for me), a little more air pressure and some aftermarket insoles (Spenco, Sole, etc.) the shoe would be competitive and worth owning a few different pairs.  Fortunately, my credit card doubles the factory warranty as long as I save the invoice, so I can live with that.  And the air pressure seems to vary from shoe to shoe.  I bought 3 pairs, one for my wife (men's size 7 = women's 8.5), running shoes and walking shoes for myself.  My wife's shoes seemed adequately pressurized.  And I could have tolerated the pressure in the running shoe but not the walking shoe.

The insoles that come in these shoes absolutely need to be upgraded in my opinion, they have insufficient arch support and with the low pressure these shoes need the extra cushioning that comes with better quality insoles.  Note: I always upgrade the insoles, even with Nike Air Max.

The running shoes were 12.5 (too small for me) and the walking shoes were size 46.  With the walking shoe I noticed something odd - their supplied sizing chart on the Amazon Website shows that size 46 = US size 13.  But when I emailed the seller they advised that 46 = size 12.  But I found that they were identical to the size 12.5 running shoes in fit - just a half size too small.  Apparently, there is some confusion regarding the sizing in their customer service department.

If they ever do produce a size 13 US I would try another pair.  But I have my doubts that even with the upgraded insoles they would be as supportive or comfortable as the Nike Air Max.  Time will tell, I would love to be proven wrong.
