"The TX4 has quite a high volume overall. The width is interesting, with a fairly narrow heel and mid foot but quite a flared-out shape towards the front, and a wide rounded toe..."
I've been very impressed with their all-day comfort. But the only way to be sure they'll work for you is to try them on
I'm on my 4th pair. They are super comfy, I have a narrow heel but quite a wide foot and toes. I wear my normal street shoe size in them.
The only problem is the rubber doesn't last that long. I get about 9 months to a year out of them before all the tread disappears, but I do wear them daily. I hear that they are bringing out a pro model in the future with harder wearing rubber.
