Yes another boot question!

These boots seem to fit the bill for me - Zappos have the measurements listed at 14" shaft height & 15.5" width for the Jane and 13" shaft height & 15.75" width for the Sabrina. These also appear to be the right shaft height for me. Can I trust the measurements to be correct? Better yet has anyone tried them or does anyone have them and can attest to these being suitable for my 15" calf?
