Wasn't sure where to post this really!
16mo DD has one or two blisters on her feet, presumably caused by her shoes I bought a month or so ago (ECCO boot-style ones). They are only her 2nd pair, the first pair were soft-soled shoes for that stage when they've just learnt to walk but aren't yet running around like mad men 
Not sure what to do. She doesn't wear shoes indoors usually, but wears them a good few hours of the day as we're always out and about with various groups and activities.
Any advice?
