I had to replace the insoles. Using the included insole it was like it didn't extend out to the edges of the instep enough before the seam of the side met the bottom and any time I would walk longer that 30 minutes or jog Id get a blister in my arch. Replacing the insoles with one that extended out over my arch area protected my foot from the nasty seam(and thus getting a blister). This brand was recommended for arch support but the shoe ends before it could provide support! The previous version of this shoe was better. Frustrating.
