This must be a bizarre question, however its quite significant.
Probably the best time to buy shoes is the evening time.
Because the foot is swollen during the evening time i.e. at the latter part of the day, and if you buy shoe at this time it is less likely that you will be buying a tight shoe. Wearing tight shoes are not healthy generally.
- Why our foot swells in the evening?
It’s because of the pooling of the blood during the whole day at our foot due to gravity.
