Given Shoe Last Maker is free to use, there is no free support included with your use of the plugin. There are, however, free tutorial videos. If you encounter bugs or have feature request or a quick question, please feel free to send them to me via the contact page. Please also note that, while there are templates you can purchase, they do not come with free support.
Eventually, I hope there will be dedicated support and training for Shoe Last Maker. In the meantime, I can provide some degree of training and support on a paid basis. If you would like to book some time with me, please do so in my calendar here.
