No, directional footstraps should be completely symmetrical.. equally easy to use from either side. Good ones are hard to find since most straps are made for twin tips and are not symmetrical.
Here are some NSI ones from bigwinds.com, although I have not tried these. If your can find the North ones anywhere. they are comfy.
