Dude. You're gonna have to suffer at first. No matter what you buy. If you've been riding in shoes, EVERY boot is going to feel like shit, be uncomfortable and "unrideable".
I wore boots from day 1. Anything else just does'nt feel right to me.
I have a set of Thor T20s. Cheap. They are about 4 years old now. They feel just as comfortable as my sneakers.
You just have to deal with it for a while. Wear them around the house, do squats in them. Bottom line, RIDE in them. Stick with ANY boot and they'll grow on you. I've seen some nasty carnage from folks not wearing boots.
