8 Month Update: Still love these shoes! I got the pink ones too, because they're pretty. Still no cracking on the sole, and still just as comfortable. I haven't had a single issue with my feet or legs, and actually look forward to changing into them when I get to work.I depended on the reviews when choosing the size. This is the first time I bought my regular size vs half size larger, and they fit perfectly. If you wear heavy socks, I would suggest going up a half size, though. I do change the insoles in all my shoes as soon as i get them, which take up a little more room than the thin pad that comes with these shoes. One thing these have that i've never seen before is a nubby, built in gel support heel pad. A very nice and clever addition. I've never bought Puma's before, I've always stuck with the recommended brand for people with foot issues, but had problems with them cracking across the bottom. The sole of these does not have a linear extruded pattern in the rubber that will contribute to this being an issue, but I will update my review if it does the same. I've been wearing them for 3 weeks, enough time to give a better review. They felt great as soon as I put them on. Plenty of room in the toe box, can't feel the steel at all and room to wiggle my toes.I work in a warehouse and walk on concrete 8 hours a day and I'm very hard on my safety shoes. Usually go through 2 pair a year. I've started using a shoe horn to hopefully eliminate the wearing/tearing of the heel materials, which is a problem i've had with all my previous shoes. I can't go without saying how amazing they look. (usually the first on the everyone's list, but is just a huge added bonus for me). They look like regular sneakers, can't see the bulky toe box at all. They're breathable, flexible and extremely fashionable. The weight feels more like composite than steel. I wouldn't think twice about wearing them outside of work, except they're not waterproof on the tops.
