@Tactim: this Panda has never had a problem with the Polysorb Total Support squeaking. That reviewer most likely "achieved" the squeaky problem by heating the insole. Though Spenco says the insole is heat moldable this Panda would not do it. The foam of the insole is not dense enough to take heat molding, at least not for any effective heat molding. Not like Softec Ultra insoles which are very heat moldable. Best just to let the foot create a natural mold over time. Relative to other supports, the only problem Panda has is the thin silver, plastic heel support piece breaking at the edge. Even when broken, you won't notice and the insole still performs. Panda still thinks the Spenco Polysorb Total Supports are the best overall insole for badminton, especially for the price.
