It does, yet it doesn't. If someone was so ill, and near to death with swollen limbs, they would be horizontal & in a bed...and clogless.
Also, if someone was suffering from major swellings of the foot, fundamental common-sense and self-evident logic would dictate that they wouldn't be wearing ANY footwear.
Finally- unless someone had paraphlegia or othe significant limb nerve loss of sensitivity, how could/would this happen in near-instantaneous time?
