I’ve had a number of the old Vivo Breathos. Liked’em but the lugs wore down too quickly.
The new replacement Vivo, the Primus Trail appears to have a more durable sole (mine were too small so had to sell before I wore them much) but the shoe had a strange plasticy feel for the lack of a better term. I may try again, in a larger size if I don’t find anything else.
I have a pair of the original Carsons. Grew to like that shoe but the sole wore faster than I thought it would and what little traction it had turned to virtually non-existant. Carson has a new trail tread that looks good.
I have a pair of Altra Superior 1.5’s that I took the rock plate and insoles out of. I prefer its foot bed and toe box over any shoe I’ve had. Really like them! But the traction is seriously lacking… and the shoe has run over a bit on the inside (i bought them used).
I’ve been looking at the Altra King MT 1.5 online… but it looks as though one can not take out the insole or rock plate which would kill the deal for me. If this is not the case, someone please correct me.
I want something low and zero drop with a big toe box and lots of traction.
Anyone have recommendations?
