Thanks for posting! These are awesome videos. I am not in footwear but have always loved the category and was extremely particular about my basketball shoes and fit when I played. You made a comment in the Alphafly review video that got me thinking about the spec’ing/designing of a last. I too have noticed that the instep width has been shrinking a lot in recent years. I kind of felt like the dimension just didn’t get scaled well when the design was adapted to my giant size 13 vs the more normal 9ish sample size. That all said, are last designs custom scaled per shoe size? Or do they pick and choose the dimensions that are adapted per shoe size?
Cycling seems to have found an interesting balance in this in recent years as they are now making frames with varying carbon fiber layups based on the size of the bike so that riders across the size spectrum find more common ride qualities regardless of size. That said, does the midsole density/thickness change much from one size to the next?
Thanks, Drew
