It's a bit heavy because it's silicon, but it's squishy, so I think it'll be good for buffering.
amazing product, it is really helpful and does not move in your shoes because it has a sticky area for the shoes :D and they are marked so you can cut it without any proplem for your right size:D the delivery is very quick and the product is careful packed, thank you so much! :-* you save my feets :-*
