Which is better, old mac or boa?

[Bronya]

For roadwork, the odd flat grassy field and non-muddy track...? In walk, mostly...

Which of those would twist least if boots rubbed together when the horse was tired?

Has to be one of those two - slightly flared shaped hooves at the moment due to very recent lami, but the flare is above the sole kind of so trimmer says can't trim it off!

I think different models are supposed to fit different horses best.
We have the Boas and they ahve worked well for us but we have always used them with the optional gaiters.
All of these are sold by the same company anyway.
Here's a comparison and info:

You might actually be better off with Boas for what you want, but it does depend on the shape of the feet, and some people find they're more likely to cause rubs.
