I'll admit it, I have a gripe with high heels. Firstly, it sexualizes women in a way that's unnecessary and is bad for health and posture in the long run. I find it socially problematic. However, that's not really what I want discuss here. There's even a better reason for why ladies should give up their heels when they go dancing. The main reason is that a high heel becomes a weapon and dangerous when beginner/intermediate dancers wear them on the dance floor. I've had a number of partners get speared by someone backstepping onto my partner's foot. When asking a woman to dance, I certainly take into account of this because I feel partly responsible for how she uses the weapons she's wearing on her feet responsibly. I'm glad to dance with a novice dancer wearing flats, as the worst that can happen is that I have to have a simple and overlead a bit to compensate for lack of experience. But when a novice dance has heels, she could easily lose balance when there's a change of direction and fall, fail to pivot correctly and fly off into an unpredictable direction, or take a backstep way too big and step on someone. For me, having to consider watch my partners heels when I dance is unpleasant, so I just avoid it and ask women who wear flats to dance unless they really know what they're doing. There's another downside though - heels negatively affect natural body movement. Sure it distributes your weight forward (as terrence previously noted), but it comes at a cost. When you stand on your toes, you change your center of gravity. You have to relearn how to move your body in this altered state, which is problematic if you're simultaneously trying to learn something you've never done before. Often, women will learn to execute a dance but focus on how to not fall rather than on their body movement. You can see this quite often in slot dancers, who almost exclusively wear heels. Their movements are quite stiff and generated from the joints rather than their core. While pushing the chest forward may make women's boobs look bigger, when the rib cage is pushed forwards you have to offset that by pushing your rib cage back during movements. The Shoulders often become stiff and arms wobble from the shoulder sockets instead of moving with their body. However, the biggest affect is on the lower body. Pushing your weight forward doesn't allow you to push your heels into the ground, which reduced hip movement. All too often women will move their hip sideways to compensate, which doesn't look good. Nobody seems to notice because when the chest is pushed forward and the derrier sticks out, it's all covered up. Even if women learn to overcome this, the knees are put under so much stress when you need to push into the ground from that angle, that it becomes nearly impossible to create the same full range of hip/get movement that happens when the foot is flat. Even the best dancers in the world cannot fully compensate for this as far as I've seen. Now, perhaps in ballroom dancing it's not that big of a deal since one can make an argument that the aspects of increased danger (controlled environment) and altered body movement (not a focus of the genre) are not problematic. However, dances that originated outside of dance studios aren't danced in heels (think Lindy Hop). Casino and salsa are easily in this category, they are social dances and require "Latin" movement which heels do not naturally lend themselves to. By wearing by wearing high heels, women are putting other dancers in danger and ballroom-izing social dances. To me this is a no-no and why I'm far less likely to dance as a woman to dance when I see that she's wearing heels. I know it's an uphill battle but I'd like to think that with raised awareness we can begin to shift things in the right direction.
