According to the enquiry and the oder recently, we can recommend some popular machines for you.

About toe last machine, the traditional one TH-N737MA is the hot seller. Because it's manual, with cementing, good quality and also not expensive, so it's always the most popular one.

Next is heel lasting , the model is TH-727MA. It's not so big, with cementing, also very cheap and useful. So this model is more popular than side & heel lasting machine. But if you want to save more time , labor and money. I recommend side and heel lasting with cementing, TH-668MA , TH-688MAS.  Maybe these two models are much more expensive than heel lasting, but it can last the waist, heel part at the same time, and can paste gluing, change left to right by itself and so on. For further benefit, side and heel lasting machine is a better choice.
