I've worn the Belleville 310, the Bates M-8, and the TR360. Of the three the 360s are the most comfortable by far, with virtually no break-in period. Not only do the 360s allow great flexibility (unlike the M-8, which is surprisingly rigid), but they also feel very much like running shoes. Likewise, I noticed that the TR360s were lighter than both other boots. The one drawback of the TR360s is the lacing system: no speed lacing here. It takes me between 40 and 55 seconds per boot to tighten and tie the laces, mainly due the fact that the TR360s' laces extend further towards the toe than on the other two styles of boots. Overall, these are great boots!
Very Comfortable, Slower To Lace
