I have a pair of Specialized Tahoes, the second pair I have had because I liked the first pair so much. However, the footbed will collapse over a period of time, and you will end up with the same issues as the Shimano shoes, with the ball of the foot falling into the hollow for the cleat plate.
I have just remedied mine with the credit card trick, and the improvement was instant. However, a better solution is to buy the Specalized metatarsal footbeds, which I understand are freely available in the States, but not so here in Australia.
