Here's a point to ponder. Do people in warmer countries (everywhere is usually warmer than the UK) have wider/broader feet.

I am a year round wearer of sandals, and I reckon because of that, my feet are pretty broad.
Most times I can even have trouble finding sandals with strapping adjustment wide enough.
Until we go abroad that is!

This year we came back with about six pairs of nice leathery sandal type shoes. They just seemed to fit.

This is not the first time we have done this, and slow as I may be, I am beginning to form a thoery on the subject.

Warm feet=bare feet=wider feet :-)
