The Escalante was such a hit that it’s hard to imagine it getting better, but believe it or not, it did! The 1.5 version features an updated knit with 360-degree reflectivity, increased breathability, tongue stay, new color patterns, and sleeker heel cup. This new upper coupled with that same powerfully plush feeling of Altra EGO™ underfoot creates the perfect combo of high performance and comfort. Stack Height: 24mm. Weight: 7.9 oz.
