    Does anyone have any suggestions for where I can find a picture of a sneaker last? I'm looking for a picture of an old wooden last and a more modern plastic last. I couldn't find anything on google but maybe I was using the wrong search terms. Thank you!

  2. Ann, type in "shoe last types" into google "images". Here is one of the many I found in my 10 seconds of searching.

    None of those are a "sneaker" last, as sneakers are force lasted, 30 years ago they might have been for "sneakers".

    All of the lasts in those photos are for "Board/Cement lasted" footwear.

    l have come back to edit, l have found one that is still using "board lasting" today, understand this not how 90% of sneakers are made though.

    Most modern sneakers are force lasted, to keep weight & cost down, looking inside the sneaker and you will see the threads that have been used to sew the insole to the upper, the only last they see is a large Aluminum unit that is part of the injection molding process of the sole, there is always a variation some where.

    David,

    I'm not sure if you're question about location is directed to me, but I work in Reading, Massachusetts, USA.

    Thank you!

    You might be able to get into a manufacture to see for yourself?

    l could get you into a force lasted footwear factory if you were in Australia, so you could see but it looks like it might be a bit far to travel for you.

    David,

    I'm not familiar with the term "force lasted" but will look into it. Thanks for the link to the video. I wish the video was slower! It's an excellent idea to try to get into a manufacturer to see the process myself. I believe New Balance is the only company in the area. Not sure how I'd get in for a view but I will look into it! Thanks for your ideas!

    Force lasted is how most runners are made, a light weight material, sometimes cloth, is used as an insole which is stitched to the uppers feather edge, no lasting margin over the feather edge, the product is now "forced"(more like slipped) over the last.
    With no upper or heel stiffener over the feather edge, which equals no foundations, for the wall of the shoe unless the sole comes up the side of the shoe to support it.

    If you look up force lasted you should also try the other term California lasted

    l gave a talk at pod conference last year where l had photos of the two types of construction, board and force, l will see if it is still on my other laptop and post the pics up for you

    Hope these pics help you.
    first is to show you how or where we cut the prodcuts

    Second one l have used a red marker to high light the heel counter/stiffener.

    The force lasted (left) counter and upper make contact with the soft fabric insole and doesnt go under the sole.

    Board lasted, (right) the upper and counter go under the firm insole board and the sole making a much more stable product.

    Notice how the shape is lost when the back is cut away on the force lasted product, no foundations, the manufacture of the force lasted product has dropped in a board in the product top protect the foot from the sole, it does very little if anything for the stability

    hope it helps

    Thank you very much David. I have never heard of these distinctions (force lasted with a board just placed on top vs. board lasted with the heel counter and upper extending under the board). How does one tell the difference just from looking inside the shoe? In all the talks I've heard at Conferences I've only heard about slip, board, and strobel lasts with board being defined as the upper being tucked under the board. Force lasted sounds like a slip last with a board placed on top??

    Yes, also known as Californian lasted.

    To tell the difference. look inside for the upper sewn to the insole, this may take a bit of digging around
