Interview: After Bombé Bleu (5.15b), Erwan Legrand Shows Us How to Climb Barefoot

Why It Matters

Barefoot climbing can unlock performance gains on technical, overhanging terrain, challenging the industry’s reliance on high‑tech shoes and reshaping training philosophies for climbers and gyms alike.

Key Takeaways

• Barefoot climbing enabled 5.15b ascent of Bombé Bleu
• Big‑toe pocket technique outperforms shoes on overhang
• Flexibility and body awareness improve with barefoot practice
• Home walls ideal for safe barefoot training
• Average climbers can gain better foot positioning instincts

Pulse Analysis

The success of Erwan Legrand on Bombé Bleu highlights a growing niche in elite climbing: using the body, not just the shoe, to negotiate extreme pockets and overhangs. While most top athletes depend on ultra‑aggressive rubber and down‑turned profiles, Legrand’s big‑toe monos demonstrated that raw toe flexibility can create micro‑adjustments impossible with conventional footwear. This approach forces climbers to rethink beta, emphasizing precise foot placement and ankle mobility over sheer shoe grip, a shift that could inspire manufacturers to design more minimalist, toe‑friendly models.

Beyond the headline‑grabbing ascent, barefoot training offers tangible benefits for the broader climbing community. By regularly climbing without shoes, athletes develop heightened proprioception, better hip‑to‑foot coordination, and a more intuitive sense of body tension. These skills translate to improved performance on any terrain, from gym slabs to outdoor crags, because climbers learn to trust subtle pressure cues rather than relying on shoe stiffness. For gyms, integrating barefoot days or dedicated “toe‑strength” zones could diversify programming and attract members seeking holistic movement development.

However, barefoot climbing is not without challenges. Skin durability, toe pain, and the risk of injury require a gradual adaptation period, ideally on a personal wall where falls are controlled. Legrand’s experience suggests that consistent, low‑volume barefoot sessions—five days a week in his youth—build resilience without specialized conditioning tools. As the climbing market continues to prioritize performance gear, Legrand’s story serves as a reminder that sometimes the simplest tool—bare feet—can unlock new levels of achievement.
