I need input on how traditional, non-replaceable soles (like on the Dominator shoe) wear compared to Sidi's replaceable SRS soles. The latter, while softer for supposed better traction and able to replace, they sure wear quickly, like a set a year--and at $50 +/- per set, that sucks (I'm on my third set). Do the non-replaceble sole treads like on the Dominator wear longer/are tougher? I'm thinking of buying the Dominator as my next shoe. Thanks.
