I agree, the Trailroc 235s are the best option out there right now.
I bought two pairs of Breathos and I hated them. I had to hike out a couple miles barefoot because they raped my feet so bad. The curved bottoms cause me to hyper pronate like crazy, and the footbeds feel like concrete on them.
Chris Wallace turned me onto the Trailroc 235s, and I've always hated Inov-8's Geisha foot optimized "perfromance" last, so I was hesitant, and the toe box looked narrow, but the mesh has a lot of stretch, and once broken in, I find these to be the most comfortable high traction zero drop shoe on the market.
Altras work pretty good for me also, but I dislike the huge stack height. The Inov-8s without the insoles are the perfect combination of cushion flexibility for me, with just enough insulation to be viable most of the year.
I'm pretty pissed at TerraPlana, the original Aquas are some of the most comfortable shoes ever made IMHO, but they seem to constantly be trying to reinvent the wheel, instead of figuring out what works and evolving it.
It's going to be a long time before I give any Vivo's a try again. My feet are still hurting.
