Have you tried buying a good walking shoe like new balance and have a lift added to the right shoe? Your orthopedic can refer you to someone who can measure you to determine how high a lift you would need. You will probably still use the left leg more but it shouldn’t be as bad if you use a rollator walker and have the lift. With the right lift you would find you can stand straighter and more balanced as far as the weight. I get around really well with my walker and the shoe lift so don’t give up until you have tried the shoe lift.
