Our Verdict
Nike Run Defy
adidas Questar 4
The Nike Run Defy and adidas Questar 4 are both affordable entry-level shoes, but the Questar 4 is the better choice for actual running. It usually costs a bit more and is heavier, but its taller, more protective platform and smoother roll make it better suited to daily mileage and longer efforts. The Run Defy is lighter and less cumbersome for walking, gym classes, and occasional short runs, but its thin, firm platform provides much less impact protection.

- Run Defy (Black/Anthracite - (Women - US 7))
- Questar 4 (Cloud White/Iron Metallic/Lucid Tangerine - (Men - US 9))
