Hi Andrey, as Chris mentioned, we have 2 new shoe styles that are made out of eucalyptus, however, there are still components with merino in the shoe (insole and the heel cup padding). You can replace the insole with an orthotic usually, however, the heel portion is stitched into the shoe. We'll have something with no merino later this year, so keep your eyes out!
There's a new style thats not wool but I don't know about the rest.
