What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Noticeably lighter than the previous version while maintaining cushioning and durability
- Comfortable for daily training across a wide range of paces and activities
- Good fit with brought-back flywire lockdown and roomier forefoot than past Pegasus models
Reviewers push back
- Air zoom pockets can feel lumpy or intrusive at slower recovery-run speeds
- Responsiveness falls off at very slow and very fast paces, working best in the middle range
- Tongue padding is thicker than necessary and not gusseted, which some find excessive
Reviewers agree the Pegasus 39 is a reliable, lighter daily trainer with improved comfort and responsiveness over its predecessor, though opinions split on whether the dual air zoom setup delivers noticeable energy return.
Reviewers praise
- Comfortable, roomy upper with good lockdown around the arch and midfoot
- Durable rubber outsole that resists wear well
- Smooth heel-to-toe transition suited to a wide range of runners
Reviewers push back
- Ride feels firm, dull, and offers little energy return compared to newer foams
- Update from the prior version is minor, mostly limited to the upper
- Wide version runs surprisingly generous, close to sizing up unintentionally
A dependable, well-cushioned daily trainer that plays it safe with only minor upper tweaks over the previous version.
Some reviewers feel dramatic pop from the dual air zoom units, others notice minimal difference from previous foam-only setups
One reviewer found the ride boring and unresponsive while another called it the best version in years
