DD1 has smelly sweaty feet (actually she sweats a lot in her sleep too) and often after kinder her feet & shoes smell.

I'm worried she's going to take her shoes off at kinder & get picked on.
What can we do for her?

She wears rio kids socks, shoes are Kmart runners or just normal kids slip ons.
Sandals or thongs.

Am going to ask kinder if she can wear sandals instead of runners but she won't be able to in winter or with pants.

IDEAS PLEASE??
