Wound Care? 6 weeks post op

I am 6 weeks post-op. I for the life if me can not get this wound to close up.We have found out that i have big reactions to medical tape/bandaids. I was using guaze wraps but found the wound would scab over and then the scab would get ripped off with the guaze. The week and a half I have been doing socks only, and trying to give it as much air as possible. The issue I'm having is now that I'm walking even when it scabs up overnight, by the time I walk around all day it looks like this again.

Any suggestiosn/thoughts? Does this seem like it's getting infected? I'm not sure what a normal level of redness is after a surgery, and the on call wasn't super helpful last week. Should I call again?
