How important are wedding shoes?

Ladies, how much thought/money did you put into your shoes? I thought this was such a minor detail, mostly because my dress is floor length and no one will see my shoes (I think). I was honestly going to use a pair of wedges that are comfy (but definitely don't match my dress). But my mom and BM are encouraging me to go high class since they think the shoes are an important detail that people will pay attention to. Thoughts??
