Updates to Zoot Ultra Kiawe 2.0

  • The very minor modifications of the 2nd version of the Kiawe show Zoot’s reluctance to change something that has gained quite a following already. A closer look would show that the new version features a mesh with wider holes for enhanced breathability. Zoot also informs runners that this mesh is of better quality than the past version.
  • The second change is also very minimal; one that may go unnoticed by those who are not familiar with the Ultra Kiawe. There is now a slightly lower ankle collar in the Kiawe 2.0 to respond to past concerns regarding ankle rubbing or irritation. The update should enhance the comfortable feel while wearing this shoe.

Size and fit

The fit and sizing of the Kiawe 2.0 are regular and resemble those of the original. This offers a sock-like fit that hugs the contours of the heel, midfoot, and forefoot. There is just enough room in the toe box for the toes to splay. Runners who want to wear socks may want to get a half a size up. Available widths are D and B while sizes are 7 to 14 for the men’s and 5 to 12 for the women’s.


The Zoot-exclusive ZCR is a sturdy carbon rubber located in the usual high-prone areas to limit wear and tear. Zoot also uses their own configuration of rubber treads called the ZPU to enhance the shoe’s grip on the track or road.


The midsole of this Zoot shoe is composed of industry grade EVA that Zoot proprietarily calls the ZVA. It spans the entire length of the shoe and provides decent cushioning and responsiveness. A carbon fiber shank is located in the midfoot to help with the toe off and to add torsional stability to the shoe.


The fit and feel of the Barefit Technology make sockless running an excellent option for the Ultra Kiawe 2.0. A Dri-Lex fabric basically covers the interior portion of the shoe for hygienic purposes and very plush next to skin feel. An Ultra Tri Sock liner adds comfort and cozy feel while the Z-Bound insole adds more responsive features. Zoot uses the Quick-Lace System in most of their triathlon shoes, including the Ultra Kiawe 2.0. The tongue loop and heel tab provide convenience when wearing or taking off the shoe.
