After 4 yrs. in Tech 3's Santa said I could go and buy some new boots.
Tried on the Tech 8's, like Okie said, thought the bootie was a hassle, and they seemed very bulky.
Then tried on the 6's, very comfy, without the bootie hassle, and with a lot of support. They came home with me.
Two weeks later went for my first ride ( ~3Hrs. ) and had a bit of trouble.
Couldn't tell where my feet were, had trouble getting under the gear lever and I had been dragging the rear brake, heating it up and fading a bit, which took a while to figure out because I had to stomp on it to know for certain that the brake was on.
Went out Sunday for a 6hr ride, still felt stiff when I put them on, but a lot better.
At the end of the ride, talking to the others and walkin around, (beer O'clock) I realised that the boots now felt great, they'd given me no trouble during the ride, only feeling slightly vague early on, and they now flex and feel great.
Despite some early reservations, I am now very happy with my Tech 6's.
