What the model says

Carve radius, to scale

  • Sidecut radius: 20 m
  • Carve radius at 30° edge: 17.3 m
  • Carve radius at 45° edge: 14.1 m
All three drawn on one scale, from the same starting point. A smaller arc is a tighter turn.

Edge hold and float

  • Edge hold: 91%, Holds well
  • Float: 68%, Some float
Ticks mark where the word changes. For 90 kg at 188 cm: hold on groomed snow, float in powder. Model figures, not measurements.

These are the model’s numbers, not measurements. Carve radius comes from the sidecut, so it does not change with weight; edge hold and float do. Flex and camber are our estimates (see “What the model uses” below).

By ability

The Zai Laisa at 188 cm for a 90 kg skier on groomed snow. Reviewers are mostly experts, so read the left of each band for what most skiers get.

Edge hold

On firm snow, 188 cm
  • First-timer: slides (17%)
  • Beginner: slides (37%)
  • Intermediate: on the limit (64%), assumed level
  • Advanced: holds well (86%)
  • Expert: holds well (91%)
assumed intermediate: on the limit (64%)

Float

In soft snow
  • First-timer: some float (52%)
  • Beginner: some float (55%)
  • Intermediate: some float (59%), assumed level
  • Advanced: some float (63%)
  • Expert: some float (68%)
assumed intermediate: some float (59%)

Ease

How forgiving it is
  • First-timer: manageable (53%)
  • Beginner: easy (100%)
  • Intermediate: easy (100%), assumed level
  • Advanced: easy (81%)
  • Expert: manageable (71%)
assumed intermediate: easy (100%)

Our model, run with working assumptions about how each level skis (edge angle, speed, how much weight reaches the edge). Not measurements. The marked cell assumes an intermediate skier; compare with your own details to see your own level.

Who it suits

It suits

  • 90 kg, advanced, all over the mountain284 of 1009 skis in the catalogue for this skier.
    • Carve radius about 17.3 m at 30° edge and 14.1 m at 45° (188 cm)
    • Strongest here: turn shape. Even its weakest part, float, is solid.
  • 110 kg, expert, off-piste in soft snow287 of 1009 skis in the catalogue for this skier.

    It doesn’t suit

    • 70 kg, intermediate, on groomers797 of 1009 skis in the catalogue for this skier.
      • Carve radius about 17.3 m at 30° edge and 14.1 m at 45° (188 cm)

    Ordered by what fits this answer. Partner links say so on the row, and a fee never changes the order.

    Where to buy

    No shops to show for this ski yet. When we list one, it appears here with the reason it was picked.

    Where these numbers come fromzai.ch, edgelab.ski, read 15 Oct 2026· “est.” marks ours

    Numbers come from the maker’s own pages, with the date we read them. “est.” marks a number the maker does not publish: ours. “from” marks a number the maker does not publish that another source does (a retailer, or an earlier season of the same ski).
