Grass skiing (also written grasski) is a summer alpine sport in which skiers ride specially designed wheeled skis down grass-covered slopes. The technique, the equipment geometry, and the physical demands are nearly identical to alpine skiing on snow — which is exactly why it has been used as a year-round training tool by competitive alpine skiers since the 1960s, and why total beginners with a ski background can link turns on grass within their first thirty minutes.
What Are Grass Skis — and How Do They Work?
A grass ski is a compact, boot-mounted device built around a continuous belt of small plastic wheels — sometimes called a caterpillar or tank-track design. The frame (aluminium on recreational models, carbon on race models) runs the full length of the ski and carries a steel edge along each side. The binding clips directly onto a standard alpine ski boot sole — no special footwear, no adapters.
The wheel belt does two things simultaneously: it rolls freely in the direction of travel (giving the ski its glide) and resists sideways movement (giving the ski its edge-hold). Roll the ankle inward to put the steel edge into the grass, and the ski carves — exactly the way it does on snow. The physics are the same. The muscle memory transfers directly.
Key components of a grass ski:
- Wheel belt (track) — hundreds of small nylon wheels on a continuous belt; the primary contact surface with the grass
- Frame — aluminium (recreational) or carbon layup (competition); length determines speed and carving arc, stiffness determines responsiveness
- Steel edge — full-length steel edge identical in function to a snow ski edge; enables carved turns and speed control
- Binding — standard ISO 5355 alpine sole compatibility; your existing ski boots work immediately
Lengths range from 65 cm (young beginners) to 105 cm (FIS competition). The rule of thumb is the opposite of snow skiing: start shorter. A 70–75 cm ski is easier to pivot, easier to stop, and builds confidence faster than a longer ski. You move up in length as your technique develops.
How Is Grass Skiing Different from Snow Skiing?
Less than you might expect. The stance, weight distribution, edge initiation, carving arc, and pole timing are essentially identical. If you can ski a groomed blue or red piste on snow, you already know 80% of grass skiing technique.
The meaningful differences are:
- Surface feedback — grass is slightly more reactive than groomed snow; micro-terrain variations (tufts, bare patches, slight moisture) affect grip more noticeably. Good body position matters more.
- Speed on wet grass — damp or wet grass is significantly faster than dry grass and also very slippery. Beginners should always start on dry slopes.
- Shorter skis — recreational grass ski lengths feel much shorter than equivalent snow ski lengths. This is normal; the geometry compensates.
- No lifts — most grasski slopes are hiked back up, though some dedicated venues have tows. Sessions are typically shorter and more intensive than a ski day.
Competitive alpine skiers often report that the forced attention to precise body position on grass — because there is no forgiving soft snow to compensate for errors — actually improves their on-snow technique. It is not a substitute for snow skiing; it is a complement that makes you better at both.
What Does FIS Approval Mean — and Why Does It Matter?
FIS (Fédération Internationale de Ski et des Sports de Glisse) is the international governing body for skiing and snowboarding. Grass skiing became an officially recognised FIS discipline in 1978 and has had a World Cup circuit and World Championships ever since.
FIS approves specific ski models for use in sanctioned competition. This approval process tests the ski's geometry, construction, wheel specification and safety characteristics against defined technical standards. A ski that carries FIS approval has passed independent third-party technical review.
For a buyer, FIS approval has two practical implications:
- Competition eligibility — only FIS-approved skis may be used in FIS-sanctioned races, from local national cup events up to World Cup level. If you or your child intend to race, FIS approval is a requirement, not a preference.
- Quality assurance — FIS approval is an independent signal that the ski has been built to a documented specification and tested accordingly. For a first-time buyer unfamiliar with the market, it provides meaningful reassurance.
The Grasski.net Model Race and Model Race Carbon both carry full FIS approval. The Model Stars carries FIS approval specifically for youth competition categories. The Model Easy is designed for recreational use and does not require FIS approval.
Is Grass Skiing Safe?
Grass skiing carries broadly similar risks to alpine skiing. The same safety mindset applies: wear a helmet, use poles, build up gradually, and respect the conditions.
Recommended safety equipment:
- Helmet — mandatory at all organised events; strongly recommended always
- Gloves — protect hands in a fall; grass abrasion is real
- Long trousers — ski trousers, softshell or hardshell; prevents grass burns
- Ski poles — standard alpine poles, same usage as on snow
- Back protector — optional for recreational, recommended for competition
The most common beginner errors that cause falls are leaning back (identical to the beginner error on snow) and attempting wet grass before building confidence on dry. A slope in good condition with a flat, obstacle-free run-out is the safest environment to learn.
What Kind of Slope Do You Need?
A grasski slope needs to be grass-covered, mowed short and even, and free of obstacles. No special infrastructure is required beyond this. Many ski clubs run sessions on regular hillsides that are grazed or cut during summer.
Practical requirements:
- Gradient — 5–20° for beginners; up to 35° for competition
- Length — 50 m is enough for a first session; 150–300 m for proper training and racing
- Surface — short, dense grass is ideal; avoid bare patches, rocks, exposed roots
- Run-out — flat area at the base to decelerate safely; critical for beginners
Dedicated grasski venues exist across Czech Republic, Austria, Germany, Italy, Japan and other countries. Between these, many alpine ski clubs prepare a nearby hillside for summer sessions — often the same location used for dry-land training in winter preparation. Finding or setting up a grasski slope is significantly simpler than finding snow in summer.
What Does a First Session Actually Feel Like?
Most people with a skiing background describe their first time on grass skis as a pleasant surprise. The skis feel short and unusual underfoot for the first few straight runs. Then something clicks — usually around the first successful linked turn — and the muscle memory from snow skiing takes over.
A typical first session runs like this: fifteen minutes of straight runs and wedge stops to get comfortable with the speed and surface; another thirty minutes of single turns in each direction; and by the end of the first hour, most beginners with snow experience are linking turns continuously down the slope.
The honest comparison most people reach for is groomed piste on a sunny summer day — familiar movement patterns, slightly heightened feedback from the surface, and that specific satisfaction that comes from making a clean carving turn. Except it is July and you are wearing a t-shirt.
