To Tie Guy:
I understand where your coming from. I can't wear leather due to the firmness of the sole and tried the red brick sole but that was still too firm and picked up the crepe and they are great for my feet and back. I now have gotten used to the chunkiness of the crepe and now prefer it. I think the crepe is more casual which works well for 90% of my attire. I also think I have less competition in the 9D TTS if I can accept Crepe soles because the competition is fierce in 9 D world!!!
I still need to try the Commando sole, the only option i have yet to wear for more than a few minutes.
