What Is the Castiron Grip Little ALIEN?

The Castiron Grip Little ALIEN is the slip-on kids beginner climbing shoe in the Castiron Grip lineup — built for the very youngest climbers who need the simplest possible shoe to get on the wall. At AU$89, it delivers a slip-on design with no laces and no velcro — just pull it on and climb. The most accessible entry point into climbing footwear for Australian and New Zealand children, alongside the velcro HUG.

Full Specifications

Slip-On Design — Maximum Ease of Use

The Little ALIEN's slip-on design is its defining feature — no laces, no velcro, no fiddling. For very young children (ages 2–8) who are just trying climbing for the first time, the slip-on design means they can get their shoes on and off independently without any help from parents. The stretch upper conforms to the foot for a snug fit. For children who want a more secure fit, the HUG with its velcro strap is the natural step up.

Flat Comfortable Sole

The Little ALIEN runs a flat, comfortable sole designed for growing feet. No aggressive downturn, no cramped toes — just a comfortable platform for young climbers to build confidence on the wall at Australian and New Zealand climbing venues.

Rubber & Grip

The Little ALIEN runs an all-round rubber compound across the full sole — grippy enough for indoor wall resin holds and outdoor Australian sandstone, quartzite, and New Zealand limestone beginner routes.

Kids Sizing Guide — Australia & New Zealand

The Little ALIEN is available in EU 25–35. Size true to your child's foot measurement — the stretch upper accommodates slight size variations.

Formerly Rock Planet — Now Castiron Standard

Kids Slip-On Climbing Shoes in Australia & New Zealand — 2026

The Australian and New Zealand kids slip-on climbing shoe market is a niche but important segment — for the very youngest climbers (ages 2–8) who are just trying the wall for the first time, a slip-on shoe removes every barrier to getting on the wall.

For Australian parents taking very young children to Climbing Australia taster sessions or commercial walls, the Little ALIEN's slip-on design means children can get their shoes on and off independently between routes.

The all-round rubber performs on all commercial wall surfaces as well as the sandstone and quartzite that defines Australian outdoor beginner routes. As your child's climbing develops, the HUG is the natural next step with its velcro closure.
