What makes you think SA? Or even period?
All I can say for sure is that Continental did make rubber heels and other products (including tires) during the Third Reich era. Any markings inside the boots? NH
There is nothing to connect these shoes to the SA. As I repeat myself over and over, the purpose of this forum is to be educational and not a free appraisal service.
