These sandals are much more comfortable than utility grade flip-flops, but nowhere near as comfortable as well-designed sandals, such as Rider 360 Running Slides. Sadly, the latter seems to be out of production and is harder and harder to find. This Teva slide doesn't have much of an arch support, so it's strictly for short-term use. You might wear it for 30 minutes without problem, but if you plan to spend all day your sandals, you'll want a better-engineered slide, one with an arch support to cradle your foot.
