I'm using Bont Vaypor+, but I love my Shimanos(R321). I find the Shimanos more comfortable, especially on longer rides, but I love the Boas and the wrap around carbon soles on the Bonts..I can't wait for the new Shimanos...guess what?? Wrap around carbon sole and 2 boas!!! Maybe not as much style as the Bonts, but I'll bet the heat molding of the upper is going to make this the best shoe out there for sure!
