If you like a flat shoe with minimal arch support go with the bonts and buy your own insole.
If you like some toe drop in a shoe with more arch support, go with the Lakes.
I have both. Both are great shoes but I prefer Bonts. They fit my normal width/flat feet very well and the one boa is all that’s needed. The Lake’s, with the thinnest, flatest insole I had laying around from some old Newtons, make my arches cramp laterally sometimes.
Probably not the most “aero” shoe from videos I have seen testing different shoes but they definitely “look” aero. So at least you have that.
Thanks to both of you. I may not like the bont’s with the bathtub shape, I think what my feet want is some room to splay, and the bont may not allow that. The arch situation would probably rule them out for me too. I have tried out the bont tri shoe, in the non wide version, and I didn’t like it, but I can’t remember why now, other than I also didn’t like the tri shoe nature of it.
I also saw Alex Dowset’s video from this year where the bont zero was slow in the wind tunnel. I need fit first over aero haha. I guess I have to talk to lake again. My first pair from them was ultimately the MX237 which they told me was their highest volume shoe. I went up a whole size from their foot length which at the time fit comfortably, even with winter socks. Not anymore though
