From a quick look on the internet, I note that some of Loake's and (I think) Church's are made with cemented soles.
Any info would be welcome.
I think one of the issues to consider first is that construction methods often reflect the quality of their components. This obviously isn't always true. There are Goodyear-welted shoes made from total crap, and there are cemented shoes made from the best leathers. However, as a rule of thumb, it's a relatively safe assumption. Since cementing is the cheapest construction method, most shoes made this way also use inferior components.
The insoles of cemented shoes are quite likely to be made of fiberboard (essentially high-tech cardboard).
Cemented shoes can be repaired, contrary to what many may tell you. However, it is undisputable that repairing a cemented shoe is much more "risky" than repairing a stitched shoe such as a Goodyear-welted or Blake/Rapid. When the sole is removed from a cemented shoe, there isn't anything holding the rest of the shoe together. Furthermore, when you rip off the old sole from a cemented shoe, you may damage the other glued components as well. This can set off a domino effect that leads to the shoe not fitting properly afterword. The uppers of cemented shoes are simply wrapped around and glued to the underside of the insole, then the sole is glued to that. So, the sole is essentially glued to the uppers themselves.
It is the norm for cemented shoes that are made of cheap materials to simply be considered "disposable" because the cost of repairing them is generally not worth it considering the deterioration of the other cheap components in conjunction with the sole. When the sole wears out, the rest of the shoe isn't looking good enough to warrant investing more money in them.
