Got a couple sets of these as well as a couple of the 4.5mm Poly & a set of the Max Cork insoles to take up some of the volume & provide a bit more cushion & warmth for the winter in my new Primal Zen Suedes & all of them seem to be a direct fit w/o trimming in both pairs of them as well as my Xero Scrambler EVs.
Currently using these in the ocean Zens & the Scramblers & the 4.5mm Poly in the graphite pair & both seem to work great at achieving my aims w/ them.
These have been super comfy so far & provide a noticeable improvement in insulation w/o any significant increase in clamminess & a minor reduction in ground feel.
