These boots can sometimes be extremely costly, so you may not want to throw them out just yet.

Before throwing them out or rushing to grab a new pair, try the simple fixes explained in this article.

Let’s jump right into learning how to fix cracked rubber boots.

How to Repair Rubber Boots

Fixing Cracks in Rubber Boots

This method does not require any fancy items, all you need are some basic tools and materials.

Things you’ll need:

  • Warm Soapy water
  • Clean cloth
  • Painter’s tape
  • Fine-grain sandpaper
  • Gloves
  • Paper
  • Stick or brush
  • Urethane adhesive


  1. Clean the exterior of the boots using warm soapy water.
