I am just used to them. standing in them isn't as comfortable as standing bare foot, but walking feels fine. No big calves or anything like that. In fact if they did do that I'd throw the shoes out, because that would mean they are putting strain on my muscles when I want my muscles to heal. Anyway, I might get new shoes, since these are alittle worn out. What shoes do you guys where for everyday walking and standing? Those Earth shoes are like $100. I was thinking about getting chuck taylers and putting dr. Scholls inserts in them (the ones for knee and lower back) and taking the inserts out when I goto workout. I don't goto a gym yet, but I might start in afew months. Right now I just workout bare foot at home.
