Lol at all the above.
Funny-shaped feet are no problem to me - I have a bunion on one foot and a scar on the other where one was removed. Not that you'd ever get me in flip-flops 'cause I can't stand the toe post thingummy.
What makes me cringe, though, are the cracked, hard-skinned, hanging-off-the-back heels of some wearers. Eugh! I shudder just thinking about them.
Mind you, I throw caution to the wind on cooler summer days. I wear loud, spotty or stripy socks with my trekking sandals. I've been reported to the fashion police on several occasions.
