SpeedShifter

The best running shoes for marathon training should balance cushioning, responsiveness, stability, comfort, and durability. Because marathon plans typically include everything from everyday miles to faster workouts and long runs, look for shoes that can help you stay comfortable while still delivering an energetic feel when you pick up the pace. Reebok SpeedShifter combines a lightweight construction with responsive HYPERFLOAT foam, a dual-density midsole, and a carbon plate for a cushioned, propulsive ride.

The all-new SpeedShifter is Reebok’s lightweight, responsive running shoe engineered with speed in its DNA. A carbon-plated, dual-density midsole combines springy cushioning with stability, while a pronounced FLOWZONE forefoot rocker helps create a smooth, fast-feeling transition through your stride. A breathable, minimalist upper and lightweight rubber outsole round out a design made to help runners find their flow.

Carbon-plated running shoes can be a useful part of marathon training, particularly for tempo runs, speed workouts, race-pace sessions, and long runs with faster efforts. SpeedShifter pairs its stiff carbon plate with HYPERFLOAT foam for high energy return and a propulsive toe-off, helping deliver an uptempo feel without sacrificing cushioning or support.

Yes. SpeedShifter is designed with the cushioning, support, and durability needed to go the distance. Its dual-density midsole delivers a balance of cushioning, bounce, and stability, while an internal heel counter and cushioned collar provide additional comfort and support around the heel.

Marathon running shoes should feel secure through the heel and midfoot while leaving enough room in the toe box for your feet to move comfortably, especially as they swell during longer runs. Look for a fit that feels supportive without creating pressure points or excessive movement. SpeedShifter’s internal heel counter and cushioned collar help provide a stable, comfortable feel around the heel.

SpeedShifter brings together lightweight materials and responsive running technology to create a propulsive feel. HYPERFLOAT foam provides high energy return, while the carbon plate adds stiffness for a powerful toe-off. A sculpted midsole with a pronounced FLOWZONE forefoot rocker helps you transition forward smoothly, and a lightweight rubber outsole provides reliable grip as you shift into a new gear.
