When adidas announced Boost as their latest technology, I honestly thought that they were on to something in terms of changing the paradigm. They had created a material that would challenge the ubiquity of EVA as the stuff that was on the bottom of every pair of running shoes (excluding the most minimalist of minimal shoes which have no cushioning at all). But as with all technology, the proof is in the pudding. How would Boost stand up to millions of miles of running? What would runners think of it? Would it become the default cushioning material for running shoes everywhere in the way that EVA had in the past?
My personal Boost experience
Personally I think that Boost is brilliant. It is firmer that a lot of the EVA that is found in trainers. And what I really liked is that now it has found its way in to the adios adiZero – my marathon racing shoe of choice – there is what I think is the perfect balance of weight, cushioning and firmness.
In fact in all the adidas shoes that I have had the chance to run in, that have Boost in them, I have found the material to be just about right.
As an aside, I think that when the adizero Prime Boost came out, adidas had come pretty close to the perfect racing shoe for me: low-profile Boost cushioning with around 9mm drop, durable rubber outsole and a flexible breathable upper. Only problem is the price at the time of the launch – £185!
Now Boost continues
Today adidas have announced the next chapter in the Boost story – the Ultra BOOST. adidas tell me that this trainer features 20 percent more BOOST cushioning material which they claim has the highest energy return cushioning in the running industry.
The shoe looks pretty amazing and there is a very sumptuous video to go with the launch. As soon as I can, I will run in the new Boost shoe and post a review, but for now… enjoy:
