Different models, different buying decisions
These are separate models, not necessarily direct replacements. Both sit in the daily training category, so try them for the same session before judging fit and feel. A specification comparison cannot substitute for a fit test.
Price and value—not a live deal comparison
Ghost 18: 149.95 USD; Pegasus 42: 144.95 USD. These are recorded offers, potentially from different dates, colors or clearance periods. They are not necessarily launch prices. Check both source links for matching size/width, current price and return policy before deciding which offers better value.
What this comparison cannot establish
We have not independently measured fit, outsole grip, energy return, comfort or durability for this pair. The absence of a rating is not a poor score. No universal winner, injury-prevention claim or race-time improvement is inferred from carbon construction, foam classification or stack height.
