Using a hairdryer is another effective way to make your Safety rubber boots wider. But, keep in mind that your boots can be badly damaged and start to melt under high temperatures, so avoid heating them too long. Though this method is quick to get stretching results, it might not be permanent.
Here is how to do:
First, put on a pair of thick socks, then the boots for greater stretch and avoid burning yourself.
Turn the hairdryer on and target it at the specific areas you want to stretch for 20 to 30 seconds. Keep the dryer 10 cm away from the boot.
Walk till your boots cool down. Keep moving your foot around or flex your foot until the boots lose the heat for better stretching.
Repeat the process if needed. Continue to heat and walk till you get the desired size.
