Adistar Boost M Chill

I bought it for my son’s xc season. He had to run 4+ miles per day, 5+ days a week for the season. He had Nike FreeRun last year and kept twisted his ankle. He really felt the difference for Adidas’ Boost tire sole and traction. It’s an excellent choice for the price and performance. The only strange thing was the different color bottom sole for each shoe. Perhaps it’s the new fashion…
