FlashSprint 3.0 Carbon Plate Running Shoes

A unisex road running shoe made for runners who want a light, responsive feel with breathable comfort and a secure fit.

Why runners choose it

  • Breathable upper: Helps airflow move across the foot so the shoe stays comfortable through warmer runs and longer training blocks.
  • Cushioned step-in comfort: Soft underfoot cushioning helps reduce harshness while keeping the ride practical for regular training.
  • Road-ready grip: Designed for paved routes, treadmill work, gym sessions, and daily training surfaces.

Available in Neon Green, Orange/Blue, Blue/Purple, Purple/Orange, Light Blue, Light Pink, Navy Blue, Red/White, White/Blue depending on selected size availability.

Current sizing is shown in UK sizes, from UK 3 to UK 9.5 for this model.
