I currently own both laced Shimano SPD with 17,000+ miles and Five-Ten Boa, also SPD.

The Shimano needed to have the sole glued back on with Shoe-Goo. First the heel to the cleat, then a year later, the toe to the cleat. 17,000 miles on these shoes & it's etting time for insoles. Not bad for $12 shoes of unknown age & mileage found at a Goodwill Industries retail outlet. I think they needed laces a few years ago.

The Five-Ten's needed replacement Boa cables & dial on the 3rd use. After fitting a free warranty replacement mechanism they seem fine. I think they need to be tightened a few clicks mid-ride, every ride. But I never thought much of it. Boa offers replacement hardware forever, indefinitely. So that's a positive as far as I'm concerned.

I think the thought provoking thing is: Neither provokes much thought.
