Topo Athletic Specter 2 Review
The Topo Specter 2 is a road running shoe designed for quicker runs but cushioned enough for long runs and marathon workouts. It is versatile enough to serve as an everyday trainer and an ideal marathon racing shoe for many runners.
The original Topo Specter was a popular all-purpose road running shoe. Topo has improved upon it by making the Specter 2 lighter, increasing the stack height (and thus the cushioning), softening the ride, and boosting the midsole foam’s responsiveness. Where the original Specter was a solid cruiser but too firm for easy runs and too clunky for short, fast efforts, the Specter 2 addresses these issues, offering a more versatile, comfortable road running shoe across a broader range of paces.
The Specter 2 has a stack height of 37mm in the heel and 32mm in the forefoot, a 2mm increase from the original model. It features a 5mm heel-to-forefoot drop and an all-Pebax foam midsole. This foam, known for its soft feel and high energy return, is commonly used in carbon-plated racing shoes to maximize propulsion.
Topo designs footwear to allow natural foot function. All their shoes feature a broad, rounded toe box, providing space for the feet to spread on impact. This promotes cushioning, stability, and propulsion while reducing injury risk by enabling the feet to work naturally, strengthening over time. By distributing running stress across the feet, ankles, knees, hips, and lower back, this design encourages efficient biomechanics. The low heel-to-forefoot drop promotes midfoot landings for optimal foot function but still works well for heel strikers, offering a smooth transition.
Notably, the Topo Specter 2 lacks a carbon or plastic plate. Propulsion plates reduce foot function by taking over some of the workload, so Topo recommends using carbon-plated shoes only once a week, with functional footwear like the Specter 2 for regular runs.
The Specter 2 weighs 192g in a women’s UK5 and 230g in a men’s UK8, comparable to racing shoe weights but with enough cushioning and durability for everyday training. Propulsion comes from the toe box’s spacious design, the responsive Pebax foam, and the midsole’s rocker shape. This rocker reduces braking forces, maintains quick cadence, encourages upright posture, and minimizes fatigue during long runs.
The heel of the Specter 2 is unstructured, with no plastic heel cup. This allows it to mold to the heel’s shape, and the padded heel collar enhances comfort. The tongue, secured with two lace loops, stays in place while running. The upper is a lightweight engineered mesh that feels soft and provides a snug fit around the heel and midfoot. The forefoot is broader than the original Specter, accommodating wider or higher-volume feet while enhancing comfort and speed. Topo shoes are similar in length to brands like Altra, Brooks, Saucony, and 361. If you wear Hoka, New Balance, or Karhu, consider sizing up by half a size.
After several weeks of use at varying paces, the Specter 2 initially felt wide and bulky, especially with its extended heel flare and broad forefoot. However, the shoes proved incredibly light and cushioned, delivering a natural and smooth ride. The Pebax foam isn’t overly soft, allowing you to feel the ground and the natural spreading of your feet. The rocker is pronounced, aiding downhill momentum and providing responsive uphill performance. After 90 minutes of steady running, the foam softened slightly, enhancing flexibility without slowing me down, though this wasn’t noticeable on shorter, easier runs.
While the Specter 2 isn’t as responsive as the Topo Cyclone 2 during short hill repeats or intervals, it still performed admirably. During these sessions, the shoes felt natural and unobtrusive, letting me focus on the workout. On recovery runs, the rocker encourages a faster pace than intended, so discipline is needed. At slower speeds, the foam feels firmer but remains comfortable.
In summary, the Topo Specter 2 is a versatile road running shoe designed for long, steady runs but capable of handling various paces. It could be a one-shoe solution for most runs, aside from slower recovery sessions.
Other Considerations
Hoka Mach 6: A narrower fit with a more pointed toe box. The ride is similarly responsive. The rocker isn’t as noticeable. Available in two width men’s and two width women’s. https://www.northernrunner.com/blog/hoka-mach-6-review/
Brooks Hyperion Max 2: A firmer feel to the midsole makes these less comfortable at slower paces. So, they aren’t quite as versatile. https://www.northernrunner.com/blog/brooks-hyperion-max-2-review/
Karhu Fusion 4: A bit more of a training shoe with some propulsion rather than a fast shoe. So, better at slower paces and less responsive at really fast paces. https://www.northernrunner.com/blog/karhu-fusion-4-review/
New Balance FuelCell Rebel v4: The Rebel has a roomy toe box but, it isn’t foot shaped. The midsole is slightly softer and it has a similar rocker. You are more aware of the stack height, and it doesn’t feel as stable. They are similarly versatile in that they are comfortable at a variety of speeds. Available in two width men’s and women’s. https://www.northernrunner.com/blog/new-balance-fuelcell-rebel-v4-review/
