There is a lot of debate on whether or not Clarks are good for plantar fasciitis. Some say that they are, while others claim that the shoes do not provide enough support. I believe that it ultimately depends on the individual and what type of Clarks they purchase. For example, some Clarks have more arch support than others. I would suggest trying out a few different pairs to see which ones work best for you. If you suffer from plantar fasciitis, I would also recommend talking to your doctor or physical therapist to get their opinion on which shoes would be best for you.
