They looked familiar to me from the get-go, and a little sleuthing tells me they're just Wellgo W01s in fancier colors. Definitely SPD-compatible, but definitely equipped with a Trek/Bontrager markup. So unless you really need that oilslick finish...
I did some time on Shimano 520s (which all of this type of pedal are basically clones of) and didn't like how they worked great, then got REALLY squeaky. So I went to Look X-Tracks, and have been happy for about a year and a half, but they're starting to feel a little loosey-goosey even with brand new cleats. So I'm eyeballing either Ritchey Comp XCs or maybe some iSSi Flash, both mostly due to the availability of fancy colors.
