Why is it my 11-12 Union SL fit perfect in cap strap position but my same year Union Atlas don't? I guess I should change the straps completely.
First, make sure your straps are in the right slots. They should be in the second slot, the ones furthest away from the toe.
The SL straps are leather and conform to the boot easier. The Atlas straps are made with something else. Its a little more rigid and doesn't let the strap conform as easy to the boot. I found it gets more broken in and takes the shape of your boot the more you use them. But yeah, the SL straps are the shit.
