Nike Air Zoom Pegasus 37 Initial Take

“Half air and half regular shoe.” as told be Nelson Farris.

Nike’s longest running sneaker, The Pegasus, continues its rich running tradition and history with some old and some new. Over the last several years the Nike’s most popular running shoe has undergone major overhauls that continues make it an all around reliable trainer.

When they initially dropped on April 30th, I had purchased them right away. With the current state of the world, it was not a surprise that it would take a bit of extra time for the shoes to be delivered. I got them on May 13th and excited because the shoes I’m was running in reached 325 miles and I wanted to retire them. I took my pictures, laced them up and went on my run.

Nike Air Zoom Pegasus 37: What’s new?
1. The full-length zoom air unit has been replaced by a forefoot zoom air unit that is twice as large (4mm to 10mm). In men’s models, the PSI for the zoom air unit is a stiffer 20psi; while the women’s models, the PSI for the zoom air unit is a softer 15psi.
2. The Cushlon ST midsole foam has been replaced with Nike’s React foam. React is lighter, more responsive, and more durable. React debuted in the Nike Epic React Flyknit.
3. The flywire cables for midfoot security has been replaced with a fit band to lock down the foot.
4. The outsole has been revamped from the Pegasus 36. The traction pattern in the P37 uses squares, diamonds, and rectangles, while the P36 uses pentagons. Nike also added a forefoot flex groove that goes lateral to medial to the P37 instead of just having a heel to toe flex groove.

Nike Air Zoom Pegasus 37: What’s similar?
1. Nike continues to keep the contoured for the Achilles’ tendon.
2. The tongue from the Pegasus 36 carries over. It’s at a reduced weight, from the Pegasus 35, and it contours to the ankle.
3. Engineered mesh upper carries over.

The Unboxing:

1. You feel the React midsole upgrade compared to the P36 and P35 especially. Even though it still carries over the 10mm drop from heel to forefoot, the Pegasus 37 feels less to the ground compared to the P36 and P35. It is just more comfortable than the two previous models, and I liked the previous two models the more I ran in them. I rotated through 3 different pairs of Pegasus 35s this past cross country season.
2. Compared the Nike Zoom Fly model, the Pegasus 37 is lighter, feels less clunky. And with the addition of React, the sneaker is cushioned but the Pegasus still maintains the firmness you like in a neutral runner.
3. As Nike advertises it, it is your everyday training shoe. I wore it on back to back day and even on two a day runs and initially (since it is new) it feels cushioned and responsive. There have been some models of Pegasus in the past you didn’t want to wear on back to back days or back to back runs. This iteration, I believe, allows you to do that.
4. I loved the look of flywire. It had evolved when it was first introduced in 2008. It used to be embedded in the upper material and has since become loose pieces of string that were designed to help secure the midfoot. But if the laces came undone from the flywire it could be annoying to replace the laces through the flywire. Now the laces just go through lace loops that are fused with the engineered mesh.

1. I think the toebox of the P37 is a bit more narrow compared to the P36 but wider than the P35. I could be wrong but that is what it felt like to me. I don’t believe as big of a negative, even though it’s listed under “negatives.” I just want to make potential buyers aware when they compare to previous models.
2. Despite the engineered mesh carryover, the shoe does not feel it breathes or is a light as the P36. The P37 feels thicker and I don’t even know if my photo below can show it exactly.

Nike continues the tradition with this iteration of the Pegasus model. It’s a solid everyday training shoe. For your easy runs, some short tempo runs, and especially for your striders/accelerations and sprints. You can tell the difference the react midsole makes. The shoe feels bouncy, you feel bouncy. It was a smooth ride when I took it out for my first run. I loved how I felt in them, I felt fast (also due to excitement of a new shoe) and the traction felt good. It certainly fits the mold of an everyday trainer. Part of me wonders if I tried on the women’s version, if I would be able to tell the difference between 20psi (Men’s) and 15psi (Women’s) and I’m going to say I probably couldn’t.

There are still plenty of Nike running models to buy, test, and review that are currently out such as: Nike Zoom Vomero 14, Nike React Miler and the Nike React Infinity Run to name a few. But I do love the Pegasus 37 so far!

I’ll provide a follow-up after logging some more miles, putting it through some different terrains. You can follow the link here to purchase the Men’s version from or here to purchase the Women’s version.  You can also find them at other websites such as Running Warehouse.
