A Decent Pair (Please Critique)

Those are some great looking slippers !!!!!

First and foremost... They look good! And finally, they look comfortable.

I'm sure that I mirror many an LW member when I say we are the biggest critics of our own work.

I think you will find that if you were to look at a similar pair available in a shoe shop manufactured on mass, the quality would differ distinctly!

As Kindaki mentioned, you can buy plastic and wooden feet for shoe making, called lasts over here, I think they work out to about £100 each.

But given that each size has three widths and then you have male and female lasts, this can soon add up.

I'd be happy to trial a pair, they look awesome.

Hey Mikey,

Those do look comfortable.

Could you please be more specific about which foam you use for the liner and which resin for the sole? How do these materials hold up? What do you use for a shaping mold?

There are a lot of different expanding foams, casting resins, etc. Some are harder than others (represented by a larger Shore or Durometer number), others can be in contact with skin (like silicone).

thanks

I also think your shoes reflect very high quality. I had to look closely to see where you wanted to improve the uppers. Are you trying to mold the leather directly to your foot? If so, perhaps you could try making a mold using plaster or a molding material. Then you could smooth out the mold before trying to mold your leather to it. This would be pretty labor intensive and not suitable for production, though . . .

I would be more than delighted with what you are currently doing. I'd be interested in what you come up with.

Hi,

For the sole I use Alumilite's Flex 80 casting resine, a urethane rubber with a shore hardness of 80A:

For cushioning in the liner / sole I use Smoth-On FlexFoam-iT V or X :

As a mold material I use Alumilite's QuickSet:

When I make a mold, I first form what I want to make from good quality playdough that does

not take water to make it soft (it's oily and can be softened by warming it up). Then I pour

the QuickSet over it and let it cure. Works like a charm!

I like the Flex80 for the sole material. It is extremely flexible and durable and easy to work with.

Smooth-On's foam can be poured into a silicone mold and will expand uniformely.

Both materials work well with glues, such as Barge or Weldwood cement, but if you lay leather

with roughened surface in the mold before pouring either the FlexFoam-iT or the Flex80, they will

adhere to the leather PERMANENTLY as they cure.

I have not had any luck with silicones as actual shoe material (only for molds), as they don't glue

well at all, in my experience.

Really nice job!

still looking for donor feet?

Thanks for the update Mike.

Urethanes and casting resins are expensive, and there are so many options that one can go broke trying to find what works best. I am certain that you have helped many people with your ideas.
