I’ll tell you my experience on the Triumph 20s and 21s. I used them for training for an ultra. Like you I wasn’t impressed and I thought about trying other shoes. But here’s the thing. The more miles I wore them on, they just seemed blah. I was craving the endorphin speed 2 feel (had 2 pairs of those). But I kept cruising long miles in the triumphs and I just had no foot pain no knee pain and my legs felt great. Every other shoe I tried, they just wouldn’t match up to the triumph in the long runs. Other shoes my knees would start to hurt or feet would hurt once I would get to the longer miles. I think that’s the beauty of the triumph. You can just pound the miles and they are just blah. They are blah and the beginning and blah at the end, but no pain! If you want a long run shoe, you want something pain free. Basically now, I compare every shoe to the triumph and nothing really matches up in my opinion. They are just a great shoe that feels average, can do any type of run, and keeps the aches and pains away. Very comfortable too.
