Joma launches 126g RS-9000 racing shoe ahead of 2026 Marrakech Marathon

# Quick summary Joma has introduced the RS-9000, a purpose-built lightweight road racing shoe that weighs 126g and is positioned for race-day use. The company says it developed and tested the model at its J Lab, including testing under high levels of physical exertion. The shoe debuts in time for the 2026 Marrakech Marathon and will be offered in a Marrakech edition with race-inspired graphics.

# Key specs at a glance

• Weight: 126g (model reported by Joma)
• Heel-to-toe drop: 8mm
• Midsole technology: Light Reactive (Pebax-based injected compound)
• Plate: Internal carbon plate
• Upper: Lightweight nylon yarn reinforced with polyamide
• Outsole: CPU rubber placed only in high-contact zones

# Materials and performance intent

# Upper, fit, and underfoot design The upper uses lightweight nylon yarn with polyamide reinforcement. Joma says these materials adapt to the foot and help with moisture management. Underfoot, Joma limits heavier outsole material to the areas with greatest road contact, using CPU to supply traction and wear resistance without adding unnecessary weight elsewhere.

# Testing and intended use According to Joma, the RS-9000 was developed specifically for road racing and tested at the brand's J Lab, including trials under high levels of exertion. The combination of a low mass (126g), Pebax-based foam, and a carbon plate indicates the RS-9000 targets runners who want a responsive, lighter racing option for shorter to mid-distance road events where weight saving and propulsion matter.

# Marrakech edition details For the Marrakech Marathon application Joma is highlighting, the shoe features a white base with red, blue, yellow, and black detailing. The word "Marrakech" is printed on the side, and palm-tree motifs appear on the outsole. These are visual touches rather than performance changes.

# What runners should consider If you're choosing the RS-9000 for race day, note the 8mm drop and very light construction. That combination can suit runners who prefer a lower-drop, responsive shoe that still includes a carbon plate for propulsion and stability. The emphasis on a stripped-down outsole and a lightweight upper suggests the shoe is intended to minimise weight while keeping essential traction and fit.

# Bottom line Joma's lightweight, carbon-plated road racer that pairs a Pebax-based Light Reactive midsole with an internal carbon plate and a pared-back outsole. Joma positions it for racing environments and has introduced a Marrakech-themed variant for the 2026 Marrakech Marathon.
