Right, those prices are in line with my experience with TPU as well - usually quite cheap compared to the typical ABS/2k stuff. I just figured that with the high volume of shoes the investment in any TPU tooling would be negligible. Any plastic tooling below $10k I usually consider cheap… But I suppose the payoff times in business cases for shoes would need to be much shorter since the shelf life might not be more than what, 2 years? So cheap in one field is not as cheap in another… also I forgot about the 10 different sizes thing
