Fit = When first tried on, the left show was a little tighter than the right. Since I had meticulously measured my feet using a Brannock template, and ordered accordingly, this presented a bit of a mystery. So I measured the shoe widths and, despite them both being labelled correctly, found the fabric top on the left shoe to be slightly narrower than the right (by about 1/8th of an inch). Thankfully there was enough stretch in the fabric that after only a few days pounding on the concrete floor of my workplace, the left shoe had eased to be as comfortable as the right, and with no signs of tightness or rubbing. So 'fit as expected' Yes, but with a cautionary tale.Comfort = Totally. The excellent shock absorbency is a godsend.Support = The arch shape does provide a gentle support without being too rigid, which is a plus, but the overall softness of the shoe provides little resistance to the rolling gait of over-pronation, contrary to what the sales literature infers. Hence after a long day, the ankles do start to tire. In fairness, since my over-pronation is 'medical grade' it may be that these are not intended for that level of support.Overall verdict = Be aware of potential issues with the fit. It's essential to measure your feet using a Brannock template before ordering, especially when considering width fitting. For comfort, I can't fault them. For Support, I'd say they are fine for normal footed people, and even those whose over-pronation is slight to moderate, but worse pronation than that, and I'd say they will do for most tasks or fitness regimes, but be aware that ankles may tire after extended periods of wearing, e.g. eight hours or more.
