How should you put the belt on so that it does not shift and keeps its shape well? — Umbilical Hernia Support Belt with Reinforcement, Type-353-4, Beige, 1 pc – Toros-Group

The card contains no detailed instructions on putting the belt on: use — «use as intended», the size is chosen by waist circumference of 111–120 cm. According to the description, the stiffening ribs provide more secure fixation, and the belt helps reduce the load on the abdominal wall.

General information (not a manufacturer's instruction): a belt is usually easier to put on lying on your back, with the navel area in the centre and no wrinkles at the edges; tighten evenly — it should fit snugly but not hinder breathing or cause numbness. If the belt shifts during the day, check the size and the tension of the fastener; a doctor can show you how to put it on correctly.
