These arrived yesterday. They are pretty cool and true to size. I wore them to work today and damn they're ruining my Achilles heel. They make blisters on the back of both legs. I've owned many DC pairs but none were built quite like this one. The back of the shoe is tilted too far forward causing it to rub on my Achilles heel and now I have blisters. I only worked 2-3 hours this morning before it started bothering me, but by then the damage was already done. I have 6 hours of work left before I can take them off. Damn nightmare. I also wear normal high socks. I can't imagine what happens when I wear socks. I know I wear them all day (no options) but I'm hoping I can get them back because it's kind of bullshit. Don't pay $60 for a blood draw.
