Reflexology Practice feet

Hi all.

New to this forum and just started studying for my A&P course and practical reflexology training starts in two weeks. I know we will get hands on practical during these session and obviously hours of case studies but I would really like to learn and practice the sequence on some rubber feet at home. Anyone else done this? I know on people is preferable and this wouldn't replace that ...but I want to get comfortable with the sequence alongside this.

Anyone recommend where I can buy these from? Google throwing up some recommendations but nothing identical to what I need

Thanks xx
