Xerosis was clinically assessed with the
XAS (Garrigue et al, 2011; Pham et
al, 2002), a nine-point scale (0-8) that
assesses the amount and size of skin
flakes, scales and fissures (Table 1). This
scale was used to assess the skin on both
heels at day 0, day 7 and day 14 by the
same investigator podiatrist.
