I wear my sandals! I get VERY Grumpy in toe covered things. VERY GRUMPY!
IF feet get wet? They dry. If feet get not too cold? They warm up. I am not going to expose myself to pain in the toes if I don't need it. Ergo. It's all in the timing? Except for last year - THAT was an exception to everything.
Soo, ya either lie or obfuscate about your 'choice' of footwear! WHO really should care? Only time it'd be an issue if'n you were a top of the line MODEL! IF that's the case? I'll betcha, there are a hundred ladies here looking for 'socially accepable shoes' and will likely find you some!
Otherwise? Frumpy is OK by me! Yer feet hurt? So, you are in comfy shoes! Ergo, you aren't distracted, thus smarter because your feet don't hurt! IF I were in business? I'd do business w/ you any time! Because I know your feet at least are happy... the rest is 'other business'.
Happier feet and soon!
