YUNGPRIMEMen's and Women's Slip-Resistant Work Shoes - Nursing - Chef Shoes

Do you have a size 10 women’s? I purchased 11 and it was way too big, and next size down is 9.5. Will that work?

do they have color brown?

I am a woman's size 10 and wanted purple but there are none left in my size. When will they be available again?

I don't want them for full-time wear - only when it's raining to avoid falling on slick surfaces. Are they good for that?
