Hi this the way we do 90% of our shoe raises:-
74_1_2.jpg
First using a stab awl check the thickness of the sole right thru to the sock lining, if this is less 1/4", then don't bother trying to cut the sole off.

Draw a line all the way round where you are going to cut the sole off, this will help as a guide to keep you from cutting right thru the sock lining.

Now that the sole is cut off add yor first layer of material, We use Medium dens EVA as it is lightweight but not to soft that it will mishape.

We always use a 6mm piece first, this is to ensure a good bond with the shoe, depending on what material it is made from.

Too make the raise even lighter we punch out holes in the next layers with hole punches. make sure the holes are not in the same place on consecutive layers as this will weaken the raise, especially on larger raises.

The raise taken shape.

Now that you have enough material for the raise, mark of the heights to the raise required.

Scour the excess material so that the shoe sits to your marks while using the original sole as a guide to how it should sit.

Please note that when marking the raise at the ball joint, this must sit at a slight angle as indicated (These are where the metetarsal joints sit and are not in a straight line as most people think) this could cause the paient to walk irregular, causing more problems. Also the height for the heel should be marked at the mid point and not the back of the heel as this is where the heel will sit while weight bearing.

Now that the raise is at the correct height it is time to replace the original sole, this must be replaced as not to make the heel kick out at the back, once you have determined where the sole is to go mark it up as above and draw round the sole to get correct aliginment.

Now that the sole is secured in place Scour the job so that the heel is square at the back and blend in the sides.

This is the same principal we use on all raises no matter what height.

Hope this helps anyone out there.

Nice neat job, thanks for sharing it with the rest of the community.

I used to use Nora Astrals Lunasoft if going over 1", how does this compare with MD EVA. I found that the EVA was less flexible but I did not have to wear the shoes.

 

The punched holes I did over the entire surface, is there a reason why we should not do the forefoot or was this just an example in part?

Apart from the holes making the material much lighter it also makes the shoe more flexible, allowing the customer to bend their foot where before it was a case of swinging it.

 

Saw a pair of shoes this morning quite by chance while sitting waiting for the Nurse to come with my daily medicine :lol:

It had a 4" raise, nothing unusual about that but the material was glistening and I could not recognise it. I asked the lady if she minded if I took a closer look and I found that there was virtually no weight to it, light as a feather. the nearest that I could guess at what the material was would be some form of reclaimed plastic or polystyrene. Job was done at the hospital thats all she could tell me.

 

Any idea what this material is ?

Not Rubber or Eva. quite hard and inflexible, rigid as a rock and mystifying.

It was not a Plasizote that I have ever used, plus I was unaware that Algeo's were dealing with normal Repairers, they stopped some years ago and I gather now only supply in quantity to the Orthotic trade.

Has the situation altered of late?

 

As for the reference to the disabled Lady, some of us cant be so darn choosy, we have to take what we can get, by hook or by crook and dissabled ladies cant run away!!!. Anyway they are more appreciative of the interest , any interest shown in them. She was quite moved when I was handling her leg, made me feel like Paul McKartknee for a minute.

Still all good things come to an end and I had to screw her leg back on,screw hole took some finding though :lol:
