Our Verdict
Topo Specter 2
Topo Specter 3
The Topo Specter 3 is a significant upgrade over the Topo Specter 2. It's lighter, more cushioned, and much bouncier, with a far more energetic ride that turns the Specter into a full-bore super trainer rather than just a lightweight performance shoe. The Specter 2 is a more stable option; however, the Specter 3's performance far outshines it on every type of run. That said, if you can find the Specter 2 on sale, it could serve as a great training shoe if you want to save the Specter 3 for race day.
