The fit, explained
The low, tapered toe box rewards Egyptian/Greek shapes but can crowd wide or high-volume forefeet. The synthetic upper keeps its shape, so any early pressure won't ease much.
A classic reference point — best for narrow to average-width feet that want a locked-down, speed feel.
Break-in: Minimal break-in; the synthetic upper holds its shape and won't relax much with wear.
