In theory i would imagine that if tri-shoes are good enough for a road timetrial, they should be good enough for enduro riding on the track.
And comments 'out there' on the www indicate that, as far as general road riding goes, they are just as effective as standard road shoes.
However, since they apparenlty have a wider mouth for easier access, there's a possibility that they could be less secure for a strong up-pull? same going for single strap system.
Or am over analysing it all?
The clean designs with minimal fastening appeal from a sleek and racy look
I don't have experience, but here's what I think:
They're designed to be easy-in/easy-out; well-ventilated (for both water and air); and for triathlons, in which see mostly steady-state power outputs rather than high-power spikes.
All three make me assume that they have to make concessions in stiffness and security (the hold on your foot).
While enduro racing doesn't see the same kind of high-power spikes or stiffness & security demands as sprinting, it still has those spikes. A glance at a handful of tri shoe models and - with a grain of salt since it's just a glance - I can't imagine using 'em for enduro racing.
black one goes far, blue one goes fast, white one goes anywhere
I have mid-priced tri-shoes and pretty decent road shoes. Both pairs are "plenty secure."
The tri-shoes sacrifice a bit of fit and comfort for: 1. easy, fast, hard-to-fumble in-and-out, and 2. wet-feet friendly.
They will work fine on the track, but if you think fit & comfort *could* be a factor, then you'll strongly prefer good road shoes.
The road shoes were bought because the tri shoes, which are fine on 25-milers, repeatedly become uncomfortable after 40 miles.
