Brand Overview
Castiron Grip is a specialist climbing footwear brand built by climbers, for climbers. The lineup covers the full spectrum from very young first-time climbers (Little ALIEN, HUG) through youth development (ONE) to adult all-round and performance shoes (SWIFT, N23, PR23). All shoes were formerly available under the Rock Planet brand — same construction, same lasts, same rubber compounds — now under the Castiron Grip name.
The brand ships directly to DACH (Germany, Austria, Switzerland), Nordics (Norway, Sweden, Denmark, Finland), Italy, and across the EU. For European climbers at DAV climbing centres, IFSC-affiliated competitions, and outdoor venues from the Frankenjura to Arco, Castiron Grip delivers performance footwear at a price point that undercuts La Sportiva and Scarpa.

At €99, it's the ideal step-up shoe for European climbers moving from beginner all-rounders into more technical terrain. Tested on Frankenjura limestone, Dolomites slab routes, and indoor lead walls at IFSC-affiliated venues across DACH and Nordics.

SWIFT — Best All-Round Climbing Shoe for European Climbers
The SWIFT is the all-round workhorse of the Castiron Grip lineup — lace-up closure for a precise, adjustable fit, flat-to-moderate sole profile, and all-round rubber that performs across gym, sport, and outdoor terrain. At €99, it's the best value all-round climbing shoe for European climbers at beginner-to-intermediate level. The lace-up closure makes it ideal for climbers with non-standard foot shapes. Tested across DAV climbing centres, Nordic indoor walls, and Italian outdoor crags.

HUG — Best Kids Beginner Climbing Shoe for European Children
The HUG is the velcro kids beginner shoe in the Castiron Grip lineup — flat sole, comfortable last, velcro closure, EU 28–38 sizing covering ages 3–13. At €89, it's the best kids climbing shoe for European children taking their first steps on the wall at DAV taster sessions in Munich, Vienna, or Zurich, Nordic indoor walls in Oslo or Stockholm, and Italian junior programmes at Arco. The flat sole allows feet to develop naturally while the all-round rubber grips on all commercial wall surfaces.

ONE — Best Youth Development Climbing Shoe for European Climbers
The ONE is the youth development shoe — a step up from the HUG with a slightly more performance-oriented fit, velcro closure, and EU 30–40 sizing covering ages 5–15. At €79, it's the best youth climbing shoe for European junior climbers in DAV development programmes, IFSC youth categories, and Nordic junior competitions. The more precise fit teaches proper footwork technique without the discomfort of an adult shoe on a young foot.

Little ALIEN — Best Kids Slip-On Climbing Shoe for European Children
The Little ALIEN is the slip-on kids beginner shoe — no laces, no velcro, just pull it on and climb. EU 25–35 sizing covers the youngest climbers (ages 2–11). At €69, it's the most accessible entry point into climbing footwear for European children.
