Got a set of these as well as a couple sets of the 5.5mm & 4.5mm Poly 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.
As a confirmed tender foot who is very rarely truly barefoot, I wound up preferring either of the Poly insoles for the current season as they seem noticeably more comfortable & a bit warmer w/o any clamminess & don't seem as prone to my socks bunching or creasing on them as either the stock cork topped insoles or these, but these seem equally as well executed for what they are & I have plans to give them another go in one pair of shoes or another when the weather turns warm again.
