Decent shoe

4/5

Overall

I have been running in the boosts for about 6 years, and love the midsoles. They are the most comfortable shoes since the old Nike airsock. They are a little pricey where I live, but the price is worth it to me.

Great shoe, super durable, top performance

5/5

Overall

I have worn Adidas Boost models since they came out. This shoe is more on the fashionable end in terms of past models. Always amazed at how many miles I can get out of this shoe compared with others. Excellent to retire and use for everyday leisure (the fashionable upgrade in recent years has made this possible). Note that price paid is not reflective of list price - the 50% company store price cannot be beat.
