Any of the SC Yonex shoes should have more cushioning, the SC4 especially seems to be quite popular around here. Victor has the SH8500, which have slightly more cushioning than the 101ltd (which tbh is one of the hardest shoes I've played in so far, at least the blue&black ones). Li Ning I can't really say, as they have only one model in my size here and at a pretty steep price as well. Asics - the Gel Blade 3 is probably just a tad easier on the foot than the 101, but if you really have problems it's probably not gonna be enough. Be sure that your Achilles tendon is not involved, as heel pain is often a precursor of Achilles tendon problems (the frequent shocks aren't really doing it any good). Try to do some calf exercises, like light rope skipping and the well-known stairwell exercise. Stand on a step with the balls of your feet, your heels hanging in the air. Starting from an extended position, go down slowly until you feel a light stretch in your calves. Repeat that 15 times per set, 3 sets every day. Once the exercise gets too easy, you can do it with one leg, but be careful not to stretch too hard. The exercise has been proven to manage Achilles pain and can be done prophylactic as well. It strengthens both calf muscles and Achilles tendons and keeps your range of motion high.
