With a stack height, which is higher than the Torin, they are nevertheless firmer. I’ve had no problems with the ankle rubbing as with many reviews but would prefer a bit more. The tongue, however with zero padding is a bit annoying. I have some redness on the top of my foot after use. So far I’ve done only a half dozen three and mile runs on them. Although the redness goes away quickly I think that might cause problems on longer runs. Something I am not trying right now as I am in the taper for a marathon (yes, it is not canceled in COVID September). With a padded tongue I’d hop on buying this shoe...but. Would I recommend it? Yes with a caveat.
