I ordered my standard shoe size of 7.5, and I noticed that they felt a little big. The shoe itself appears to be the same length as my other Hoka's, but the insole that comes with the Kailua is the thin insole that is optional with the Stinsons.
I had an extra pair of the regular Hoka insoles so I replaced the thin ones, and my feet were as happy as a bug in a rug. My friend Vickie also purchased a pair of the Kailua and noticed the same thing about sizing. She, too, will be putting in a thicker insole to keep the inside of the shoe from feeling too large.
While there is still plenty of softness to the Kailua, it isn't as squishy as the Bondi B or Stinson Evo Tarmac (review). This was exactly what I was looking for. I also notice the toe box area of the Kailua seems narrower than both my Bondis and my Evo Tarmacs. They feel sleek and fast, and still plenty soft for shorter races. Strangely they weigh slightly more than Bondis. I'm not even sure how that is possible.
|Stinson Evo Tarmac and the Kailua Tarmac|
|Women's Size 7.5 (no insoles) = 7.5 ounces|
Bondi Bs = 7.4 ounces
Stinson Evo Tarmacs = 8.8 ounces
trail Stinson Evos = 9 ounces
Mafate 2 = 10 ounces
I won't be giving up my Bondis anytime soon, but I still like these shoes. While the Kailuas cost less on paper, I imagine they will cost more per mile based on shoe life expectancy. If you are looking for a shoe that is light and can last a long time, go with the Bondis. If you are looking for a shoe that feels faster, go with the Kailuas. Happy running!
