The pastor of Kingdom Baptist Church, Joey Faust preached a sermon on shoes! You can find it here.
Faust strongly attacked women's high heeled shoes as immodest and unhealthy. Its kind of refreshing to hear the kind of old-fashioned fundamentalism that has something to say about clothing. Personally, I think Christian women are at liberty to wear high heeled shoes if they wish, but I think they should at least consider whether they are really modest or appropriate.
Faust's sermon seems to have been at least partly inspired by recent scientific evidence, evidence which he referred to, which suggests that expensive running shoes are a waste of money and counter-productive. It seems the more ankle support and padding you put on your feet, the weaker and more vulnerable to injury they become. This philosophy is good news for people like me who love to wear flip flops with zero support.
Faust would have horrified the fashionistas by his suggestion that if Christian women wear sandals, they should wear socks. As much as I love Faust's preaching and endorse his ministry, I hope this idea does not catch on. I think women look lovely in flip flops with no heel.
