Overall Thoughts
The DS-Trainer 21 is a great option for runners who need a little support while they are running faster paced runs. The heel to toe transition is quick and great for those faster runs. The shoe is also a safe racing flat option for less experienced runners who have not worn racing flats in the past. If you are looking to add another shoe into your rotation of shoes give the DS-Trainer a try the next time you are in.
