Has anybody had any luck trying these on B3 boots?  I'm thinking the kinda thing you can get from Amazon, my boots are just a tad on the tight side and I'm wondering if using a boot stretcher would ease them off?

Thanks.

I would have thought very little chance of success. What are your boots made from? Leather might stretch a bit but it will be fairly thick leather on B3 boots. Synthetic materials will stretch very little if at all.

Probably more chance of creating a little extra room with different insoles or socks. Buying new socks is cheaper than buying new boots.

I use them on my climbing shoes to make them wider, needs me to use a heat gun (hairdryer type thing) to make the stretch permanent though

Have you tried with a bag full of water inside and putting in the freezer?

Haha novel idea but not one I think I'm prepared to try

I've done the usual with insoles and socks but they still feel on the tight side.
