To (temporarily) kowtow to the cult of brevity, the short answer is, “not very.”
To elaborate, most major ski brands didn’t derail the introduction of new products that were in the works well before the pandemic dropped the hammer. There’s a rhythm to the product renewal cycle that shifts the spotlight every year to a different model family within any brand’s global collection; that rhythm was largely respected despite the unique obstacles imposed on the process this year. If most of the models appearing in 21/22 catalogs seem similar to what was offered this year, it’s because this is how the line renewal machinery ordinarily operates.
What’s difficult to judge from outside the R&D pipeline is what we’re not seeing. That is, were there more new models or upgrades to existing star products ready to launch that were put on hold to avoid overloading a potentially weakened distribution network? Possibly; what might have been a planned six-model launch may have been trimmed to three or four, for example.
Happily, there’s no real downside to this scenario for the prospective ski buyer. All essential model family refreshing and line extensions will unfold as forecast. If you haven’t bought a ski in three or four years – I believe the average span between new ski purchases is over seven – the entire universe of Alpine skis is new to you. You may spot some names you recognize, but the skis that bear the name will almost assuredly be different.
