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.
The Ruck Recovery Insole is a performance-enhancing orthotic designed to fit into any footwear. It utilizes the same thermoformable foam found in our Ruck Recovery sandal allowing for a customized fit. It also incorporates a high-rebound foam heel insert and molded TPU arch support.
Forming Instructions // Remove the old insole from your footwear. Place old insole over the top of the Ruck thermomoldable insole and trim excess forefoot material from the Ruck insole. Insert the trimmed Ruck insole back into footwear and confirm it fits correctly. Remove the trimmed Ruck insole from your footwear. Preheat oven to 215° F / 100° C. Place insole in the oven for sixty seconds, use a timer. Remove from oven, insert insole into footwear, and put footwear on. Bear weight evenly on the warm insoles for ninety seconds or until cooled (no walking). Once the insoles have cooled, they will maintain their custom shape.
