MKS hasn't changed their toe clip design in eons (no need to), but they have recently responded to the fact that many of their toe clips aren't being ridden with low profile cycling shoes. While MKS's standard toe clips fit many casual shoes, they might not fit boots and other bulky shoes. That's why they created the MKS Deep Toe Clips. They have a much roomier toe box section. These are available in the standard steel in size medium and up and in the Half Clip in one size, in standard steel or leather covered.
