Agree with @M2511. Don't know where you got the McA's from, but the time to have done that was when you order them. Then its $40 for the tap sole (if I'm not mistaken). Getting them added now would not make sense financially.
If you must have more grip right now, then a cobbler can toppy them for right around $40 give or take. I think I've heard as low as $30.
Yea I know. I wanted to get the Merlot McAllister with the combination tap sole, but the leather sole McAllister was the only one available in my size and it was a closeout style so I didn't have a lot of options. I ordered it last week. Thanks though.
