Midsole & Energy Return

  • Dual-Density Foam Stack: Premium Super Boom foam on top for soft, high-energy return; foundational Boom Tech foam below for structural stability.
  • T700-Grade Full-Length Split-Toe Carbon Plate: Segments plantar force zones to reduce peak foot pressure by up to 8.5% and boost toe-off push efficiency by 4%.
  • Geometry: 8mm drop (38mm heel / 30mm forefoot stack) with an aggressive forward rocker for a propulsive, rolling transition.

Upper & Fit

  • Boom Fiber Mesh Upper: Fine single-layer mesh delivers 35% better breathability than traditional MONO materials while wrapping the midfoot securely.
  • Fit Profile: True-to-size with a roomier forefoot volume compared to the Feidian 5 Challenger; slightly tapered toe-box.

Outsole & Stability

  • Full-Length GCR (Ground Control Rubber): Provides 23% improved wet-surface slip resistance and long-lasting traction across all conditions.
  • Wider Platform: 1.5mm wider forefoot and 2.5mm wider heel vs. the Feidian 5 Challenger for a significantly more controlled and stable feel during long, fatiguing efforts.

Weight

  • Approximately 211g–220g (size-dependent) — highly lightweight for a plated trainer.
