Like all Xeros, the Gracie has a wide toe box and has ample room for the toes to splay. However, we found the Gracie to be a little snug while wearing Correct Toes due to the waterproof rubber. People with more narrow or low-volume feet will be more likely to comfortably fit Correct Toes in the Gracie compared to those with wider feet. Correct Toes that have been modified by trimming the 5th toe spacer are also more likely to fit than unmodified Correct toes.
These rain boots are completely flat, without unnecessary heel elevation or toe spring, and have a stack height of 5 mm plus a 3.5 mm removable insole. Xero Gracies are also one of the more flexible rain boots available, which helps to encourage natural foot movement. Although the rubber should soften over time, our tester observed the boot creasing across the tops of the toes, causing some mild pinching discomfort.
