Today, I’m going to review the Nike Air Zoom Pegasus 31 which can be described simply as a responsive, comfortable, and neutral trainer that is very durable and one of my favorite running shoes I have in my arsenal.

I like them so much that I have 3 pairs of them!



Nike has lately been making some incredibly good-looking shoes and these shoes fit the bill!

For men, the Nike Air Zoom Pegasus 31 comes in Hyper Cobalt/ Black/ Volt &White/Black/Volt. The color options for women feature Pink/Black/Volt & White/Bright Pink/Grape.


The upper has a completely new design. Even though it looks different, it is still somewhat similar in the way it feels. The Nike Air Zoom Pegasus 31 uses engineered mesh with overlays on the sides that secure one’s feet well without being too snug.

The padded tongue and the cushioning around the ankle collar are comfortable to run in.



The heel is pretty firm but that allows for a secure fit without being too snug. One thing that I especially like about the Pegasus 31 is that they come in a variety of shoe widths ranging from narrow to wide (4E).

The toe box feels especially roomy for the wide models and for someone like myself who sports wide feet, it is truly a blessing! If I had to compare the previous models (29 and 30), I would say that for the fit, it is snugger than the 29 model, but the 30 is still the better overall ride than the two.


The Air Zoom Pegasus 31 has a redesigned sole unit that incorporates a 10 mm drop which is supposed to give a more natural and faster feel when you are running. This change in the heel drop has made for a firmer ride.

This is something that I’m not a huge fan of since the 29's and 30's had a soft feeling to the sole, which I loved about those models. While I like the shoes a lot, this is just something that I'm not that happy with the 31.



The Air Zoom Pegasus 31 is just a chip off the block from the Pegasus line. In the 31st generation, there were some updates done to deliver an incredible ride that is firmer than previous models without completely sacrificing the identity of the Pegasus name.

They are comfortable, responsive, and durable running shoes that have lasted for a while. I look forward to seeing what the next generation brings since I loved these a lot.

My life as a runner started 7 years ago and currently, I average 60-85 miles per week. I've participated in various cross country and track and field meets. One road race that has been a tradition for my father and I, is to run in the world's largest 10K on the 4th of July in Atlanta, Georgia called the AJC Peachtree Road Race. I run for the LSU Cross Country and Track & Field teams in Baton Rouge, Louisiana.

Good to know

  • Nike reinvents the ride of the Pegasus 31 by coming up with several significant changes. The first major change is the lowering of the sole profile to give a closer to the ground feel and the start of several changes that begins a new firmness that has never been experienced before by hordes of Pegasus fans. As the sole is about 3mm lower than before, there is lesser compression, which results in a less squishy feel.
  • Midfoot security is enhanced by a new network of printed overlays. Despite the minimal upper, the security of the foot is as guaranteed as ever in the new version of the Pegasus.
  • Another change is the removal of the side grooves that helps with the compression upon impact. Without the side grooves, the transition quickly moves from the back to the front. Again, this adds a new firmness in the cushioning.
  • The last effect of the lowering of the sole is the prominence of the Air unit in the heel. Because there isn’t much compression happening by the lowered sole, the Air unit stands out with every impact as it delivers a renewed sense of pop in the 31st model of the Pegasus.
  • The upper gets the love in the new version also. Nike removed any overlays around the toe box, giving the forefoot more room. With the elimination of overlays in the forefoot, a new engineered mesh claims a rightful place in the upper as it offers better structure, even without the overlays.
  • An inner sleeve that is made of soft mesh also appears. The fit and midfoot security are immediately enhanced by this cleatie-like enhancement. Another great result with this addition is the elimination of tongue slide as the tongue is now attached to the inner sleeve.
  • The outsole is not spared when it comes to changes. A noteworthy modification is a more consistent and quicker transition because the rubber is not separated by too many cut outs. There is also one lesser flex groove. Again, it contributes to the quickness of the transition and the responsiveness of the ride without taking away too much flexibility.

The fit is of the Pegasus 31 is very familiar to fans of this line. There is a snug heel and midfoot with better room to splay in the forefoot. The volume in the forefoot is average, though. Most runners with medium to slightly wider feet can fit in effortlessly in this shoe. Medium is the offered width while sizing is standard.

The outsole is fairly full contact with consistent size in the rubber that helps the transition from the heel to the forefoot. There are forefoot grooves, but are one fewer in number, which gives the shoe a little firmner than before. Carbon rubber covers a large portion of the outsole. Nike features crash rails or twin strips of rubber in the lateral side of the shoe from the heel to just above the midfoot. The guide rails are separated by a vertical flex groove to make cushioning better.

A moderately-sized slice of compression-molded Cushlon foam blankets the entire midsole. This material is also found in the Nike Pegasus 35. As with most full-length foam, the transition is seamless and quick. Because of the lower sole, the Air bag in the heel gives a very responsive feel. The pop in the heel quickly transfers the weight to the firm midfoot and forefoot for that fast-paced run.

The upper is a mixture of engineered mesh on top for better structure. Beneath this engineered mesh is a more refined and softer mesh for that next to skin feel. This mesh goes right to the mesh of the inner sleeve. Nike uses a network of printed overlays that keep the midfoot secure. The firm ride of the midsole is compensated by a cushy insole and soft strobel. A traditional lace up closure closes the deal.
