My personal preference is for adidas and I wear only the 3-stripes.
So as much as I love the brand and think that much of it's product offering, R&D etc is fantastic, given the number and range of running products I purchase, it's also means that I easily spot areas that let it down.
One such area is inconsistent quality of the finished product and inconsistent shoe size. I won't rant on about that in detail now but suffice to say that everytime (and I mean everytime) I buy a new adidas running shoe I always buy at least two pairs of the shoe in my size so I can directly compare not only quality of the finished shoes but more importantly the SPECIFIC size. My experience is that the same size shoes can vary by upto appx 1/2 a size. I know that sound bonkers but that's what I find with about 50% of my purchases. In other words the size on the box and on the manufacturers tag inside the shoe is a guide but not definitive. There is absolutely no substitute for trying the shoes on and making sure they work for you. To be clear, I'm not saying the size on the box/shoe is wrong, rather that one pair of, say, size 10.5 shoes can feel more like 10 and another of the same show more like size 11 which must be down to the manufacturing process and the tolerences that are allowed. This is why I always buy from a retailer (esp the adidas online shop) with free return shipping so that I can return the pair of shoes that are poorest on finished quality and specific size.
As as example I recently purchased a pair of Adios 3 in Bright Royal. Two pairs as normal layed side by side and I swear one pair was 1/2 size smaller. I should have at least tried them both and measured them, inside and out but on this ocassion did not have much spare time so simply rejected the smaller (and poorer quailty) pair and sent them back.
So my advice is try at least two pairs on of the same size shoe and pick the best one for you. If no difference great, easy choice. But you'll be amazed at how often the difference is significant.
