How to confirm whether the PVC rain boots need to be replaced

Confirm whether the pvc rain boots need to be replaced, you can check and judge by the following steps:

1. Appearance inspection:

- Check the surface of the rain boots for obvious cracks, damage or deformation.

- Observe whether the color of the rain boots has faded or whether the surface material has obvious aging phenomenon, such as hardening and brittleness.

2. Wearing comfort:

- If you feel discomfort when wearing them, such as pinching your feet, grinding your feet or feeling that your shoes are becoming loose and not sticking to your feet, this may be a sign of aging rain boots.

3. Waterproof performance test:

- Simple waterproof tests can be carried out in a safe environment, such as filling the inside of the rain boots with some water to observe whether there is leakage. If the waterproof performance is significantly reduced, it indicates that the rain boots may have been aged or damaged.

4. Shoe wear:

- Check the soles for wear and tear. If the sole is heavily worn, especially if the anti-slip pattern has been blurred, it may need to be replaced to ensure safe walking.

5. Elasticity and flexibility test:

- Try bending or twisting your rain boots to see if they return to their original shape. If the rain boots become stiff or difficult to restore, the material may have aged.

6. Internal inspection:

- Check the inside of the rain boots for mold, odor or damage. If these problems occur internally, they may need to be replaced or thoroughly cleaned and disinfected.
