Episode notes
First-Time Vaporfly Reaction
- Coach Elizabeth bought a first-generation Vaporfly at an outlet for $130 and recalls the shoe felt 'marshmallowy' and unfamiliar.
- The strange soft, high-stack sensation took getting used to and felt like running on platforms at first.
Where The 4% Came From
- The original Vaporfly study reported ~4% average improvement in running economy for fast runners.
- Only a small fraction of that benefit (~1%) may be attributable to the plate itself.
Choose Comfort And Health First
- If a supershoe is comfortable and doesn't cause problems, you can use it even at slower paces.
- But prioritize the shoe that keeps you healthy and stick with what works for your training.
