INTRODUCTION

The LunarSpider R3 is a lightweight racing shoe designed for speedwork and racing.

CUSHIONING

  • To keep weight down, this shoe contains no additional cushioning technologies.
MIDSOLE
  • Full-length Lunarlon is a single density foam throughout the shoe providing a lightweight responsive ride, along with a smooth heel to toe transfer.
  • TPU Shank is a Y-shaped thermoplastic unit in the bottom midfoot for improved heel-to-toe transition.
UPPER
  • Mono Diva Mesh super light single layer mesh that provides a breathable upper. 
  • Flywire over the midfoot is made of high tensile strength fibers layered between TPU and foam for a strong, lightweight, and dynamic fit.
OUTSOLE
  • BRS 1000 carbon rubber provides durable traction.
  • Duralon uses blown rubber in the forefoot under the metatarsal area for improved cushioning.
