Why worry. As long as they are intact and serving the intended purpose. They may have gotten a slight twist during installation, who knows. This would seem to be a low order cosmetic issue. To rotate the boots, you will have to cut the retainer straps, twist them back to where you like them and apply new retainers. The tools to do this can be pricey...
