They are still colour-coded as well, they just don't use the colour for the whole surface of the insole.

I've recently bought a pair of green (+++) insoles at the nearest Specialized shop. Used their measuring device, got evaluated as medium high, but they didn't have blue ones in stock and the green still felt better than stock insoles. An important point though - I use Bont shoes at the moment, and they have built-in arch support and with them, green may be just a bit too tall for me. At the same time, in my Shimano shoes (which are a lot flatter) the green ones feel perfect. I will probably switch to blue for Bonts, but the jury is still out.

I think it's very important to try out the insoles in your shoes and not just go by the measurement on the thing at the shop. It is also important not to go by how they feel when standing or walking. In my experience, cycling shoes need more aggressive arch support than walking or running shoes and you should definitely feel it when not on the bicycle.
