Use the chart to determine your size. If you're borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.
CHEST: Measure under the arms around the fullest part of chest.
WAIST: Measure around the narrowest part (typically the small of your back and where your body bends side to side).
HAND: Measure around your dominant hand with a tape measure at the widest point (typically just below the knuckles).
FOOTWEAR: Viktos footwear fits true to length, but features a high volume forefoot for foot splay under load. Sandals are available in whole sizes only. If in between sizes we recommend going up to the next whole size.
BUST: Measure under the arms around the fullest part, across bust points.
