Specter 3
Specter 3 is Topo Athletic's max-cushioned neutral Pro Series trainer for tempo sessions, intervals, and fast long runs. Its overhaul introduces a lighter full-length RevFoam ATPU midsole, ATPU insole, and redesigned rocker for quicker toe-off. Thicker rubber improves durability and stability, while recycled mesh maintains a roomy toe box with secure midfoot and heel hold.

Weight measurement and plate details
- Weight note
- Topo Athletic US official product page lists 7.7 oz for men's M9. The gram value is an approximate conversion from the official ounce value.
- Plate note
- The exact official US product content provides a complete construction description covering the full-length RevFoam ATPU midsole, ATPU insole, rocker geometry, rubber outsole, and upper. Exact REI and Running Warehouse pages corroborate that construction without identifying a carbon structure, so carbon_plate is classified as false.
