-
A lighter, more breathable upper mesh (engineered mesh) to reduce weight and boost ventilation.
-
Slight adjustments in geometry: a wider forefoot/heel platform for slightly more stability, more sidewalls for rearfoot support.
-
The outsole rubber coverage remains robust; the tread is familiar, with improvements for durability.
Ride Feel, Performance & Real-World Experience
Here’s how the Pegasus 41 actually performs, based on hands-on testing and user feedback.
What Reviewers & Runners Like (Strengths)
-
Versatility & “do-it-all” training shoe
Many reviewers describe the 41 as a dependable daily trainer that handles easy runs, tempo efforts, and moderate long runs solidly. -
Smooth, responsive midsole
The ReactX + dual Air Zoom combination gives a lively but not overly soft ride. It’s responsive enough to feel energetic without feeling unstable. -
Upper / fit improvements
The upgraded mesh is praised for being lighter and more breathable. The padding around the collar, tongue, and heel gives good comfort. -
Durability / outsole performance
Many note that the outsole rubber holds up well, with less visible foam wear compared to many other trainers. -
Stable rearfoot & guidance
While it’s a neutral trainer, the 41 provides mild rearfoot guidance (via sidewalls) and a centered heel strike experience.
Proper Shoe Fit
Get The Right Size!
Improper shoe sizing and shape are the primary cause of ingrown toenails, bunions, corns and hammer toes. Sounds fun, doesn't it? It's not. Shoes that don’t fit your feet correctly can also lead to muscular imbalances in the body, opening the door to foot, knee and hip injuries.
The More You Know..
Most runners get shoes too small for them because they don't take into account these factors:
- When a load is applied to your foot by running, your foot will spread up to half an inch in length. One shoe size is only 1/3 inch.
- If allowed, your foot will splay 15 percent in width under load.
- Your foot is widest at the toes (but most shoes are not).
Tips on sizing
- Do not assume you are the same size as a previous shoe.
- If your feet are slightly different sizes, get your shoes to fit the larger foot.
