We use the Build a Bear shoes for Whoopie who is 28.5"
We use the low top sneakers and snug up the laces. The shoes stay on fine for the hour or so needed during a visit on tile floors. We tried the high top boots and sneakers and found they are too tall.
Here is a picture of Whoopie in her shoes during a visit last month. Whoopie and the shoes were a big hit!!
I was thinking about doing that for my minis when I drive them. I will try the build a bear ones. They have one in the mall here. I have some sandles I bought but they fall off lke crazy. I just can't stand spending $150 for old macs for a mini when they cost the same for a big horse! That just makes me crazy!!
