Where Pegasus 42 fits in your rotation
Consider it for the regular easy runs that make up most of your week. Try it at your usual easy pace; an appealing specification sheet cannot establish whether the upper, heel hold and ride suit you.
What the recorded measurements tell you
Source-checked record: 10.3 oz per shoe, 38 mm heel stack, 28 mm forefoot stack and 10 mm drop. Weight is a comparison input, not a speed prediction. Stack describes height, not softness; drop describes heel-to-forefoot geometry, not injury protection. One men's/unisex US 9 shoe, ounces; stack/drop in millimetres.
Construction and trade-offs to check
The record classifies the platform as neutral with medium cushioning. No carbon reinforcement is recorded. The catalog does not classify the midsole as super foam. Confirm toe-box room, heel hold and cornering confidence yourself; these are not established by the listed geometry.
Price, availability and when to wait
Availability not verified. The recorded price is 144.95 USD. Recorded USD price; may be colorway-specific or clearance. Not MSRP, a live quote or a stock guarantee. Compare the same size, width and colorway, including return terms. A discounted older model may be worth considering if its fit and condition meet your needs.
Before buying or upgrading
Use the series links to check the previous Pegasus model, but only draw numerical conclusions when both entries have comparable, dated source measurements. Keep a comfortable existing shoe unless the new version addresses a specific need. For a new model, verify sizing, width options, outsole and return policy rather than inferring them from weight or price.
