Heels on grass

Hi,

I haven't tried them out yet but I bought a product called Grasswalkers for my wedding shoes. It's like a plastic piece that sticks onto the sole of your shoe from the heel to the ball of the foot so it makes it more like a wedge shoe. It might be worth checking out! I think it's under $10 for a pair!

Zappos.com and look for block heels

If your whole event is on grass, I would find different shoes. You will be pretty uncomfortable all day (your weight will be carried primarily on your toes) even if you manage to find heel caps that work with your shoes. It's too important a day to be worried about how your feet feel/how your shoes are holding up.
