Love this shoe! It is more expensive than others I've had, but the toebox is soo light it has made my running so much more enjoyable! My heel feels amazingly supported and cushy; kind of wish there was a little bit more cushion under the ball of the foot, but very happy w it being so light (fair trade off). I usually run outside and these have been fantastic so far (1 month in). Definitely recommend for mild-mileage (20mi/wk) indoor or outdoor.
