(This is not an additional product but rather just a means to show more pictures). Here are some various pictures to show different types of shoes used and some pictures on how to adjust the brace shock cords. Some of the terrain I have walked on with these braces. Some of these are of a client that used the BFA in order to wear a lot of her different types of shoes. It wasn't original designed with this in mind but it appears to have worked for this client.
