City Councilor Eric Navickas - who opened the MAda Shell Gallery with partner Amy Godard - slathered a layer of red paint on the soles of sneakers, boots and sandals before people fired the footwear at an 8-foot image of Bush.
Each shot cost $1 at Friday's opening, with the funds to go toward future gallery exhibits.
Godard said the exhibit is a "statement of solidarity" with Muntadhar al-Zeidi, the Iraqi journalist who was arrested after hurling two shoes at Bush in protest during a Baghdad news conference last month.
One contributor was 91-year-old Marjorie Mather.
"Wow, I didn't know that was going to be so much fun," she said after smacking a shoe into the Bush image.
