I tried the Epic React Flyknit after reading great things about the React midsole. I had loved Boost midsoles previously for their "bounce" but had tired of some of the Adidas designs. My last Boost shoe was a Supernova that was heavy and too pillowy compared to the Energy Boost.
The React midsole seems less responsive than anticipated and I feel sluggish running in them, at any speed, although they are light as hell and the upper is really great.
I suppose I'll try to find some old Energy Boosts for my next shoe.
Not looking for shoe suggestions, but am wondering if others have felt let down by React midsole material.
