Here is an intriguing possibility. What if adidas updated this shoe (from the early 2000’s) with the addition of a Boost foam midsole?
The Response has proven to be one of the more versatile racers - light enough for a road mile, cushioned and durable enough for the longest races in your range. The only apparent changes are weight and support, in the men's model - a little less for both, but not significantly noticeable. The midsole remains the same, with minor changes to the overlays of the upper and lacing support, and most importantly the price is unchanged.
Weight: 7.1 ounces
