Otaki in Japanese Samurai slang is the oldest single wire sword: extremely sharp and precise also on small targets. A concept perfectly applicable to climbing: Otaki is a precise, supportive and structured climbing shoe, ideal for climbing in crags, on walls and boulders thanks to features that meet the requirements of today’s modern climbers. The new construction method combines the advantages of the all round snug fit of a slipper to the precision and volume regulation of a Velcro closure shoe. This solution guarantees maximum sensitivity and precision even in torsion: the shoe perfectly follows the movements of the climber eliminating empty volumes and rigid zones. The Innovative S-Heel(TM) allows to maintain perfect torsion stability accentuating performance and adaptability in heel hooks when bouldering.
