<human>: I read the FAQs and did some research but couldn't quite come up with an answer/alleviate some of my fears. Sorry in advance if I shouldn't have posted this.

I'm currently a cross country/track runner at my college, and I've been running since I was in middle school. I've been wearing Brooks Ghosts for about four years now. I've also had on and off injuries. I'm looking to switch to a new shoe, particularly the New Balance Fresh Foam 1080. They look to be about the same as the Brooks Ghost minus the heel toe drop. My question is will a drop from 11+mm to 5-6mm hugely affect my body? I know you can't give a definitive answer, but research showed me that it can help improve midfoot strike. I already have a decent midfoot strike, but I've been finding the Ghosts to be a bit heavy and I tend to fall on my heels when I get tired. I want to train myself out of it. If this helps at all as well, I wear custom fit insoles molded for my feet, so I wear a neutral shoes since stability shoes would be too much. I also suffered Posterior Tibial Tendinitis in my right ankle two winters ago, and it has recently been flaring up, also causing me to consider switching shoes. To sum it up, will the heel toe drop difference between these shoes be beneficial? Or would it possibly cause more trouble than it's worth.

Can you condense the text into three sentences or less?
<bot>: Wearing Brooks Ghosts for four years, Posterior tibial tendinitis and desire for more consistent midfoot strike/lighter shoe, should I switch to New Balance 1080?
