I got a pair of these about a month ago. They are possible to modify, but it is a bit harder than with Lavers. I've only cut the insides and the toes... First you have to remove the stripes, which is easy..
Then you cut out the thin 'net' layer from the inside, which is actually easy too, cause nothing really can go wrong as the material underneath is this thick canvas stuff.
Now you've still got two layers of material left, the thick canvas (is that what it's called?) and the thin 'net' on the outside. The difficult part is cutting out the thick stuff without cutting the thin stuff!! I recommend you just go easy. Try and slice into the canvas carefully untill you can stick a tiny screwdriver (or whatever) in between the two layers of material, and gently try and separate them from each other. You may need several tools: knife, scissors and something small and pointy(!) like a screwdriver. Those small curved nail-scissors are good for cutting the canvas out of the toe...
I hope I'm not just getting you confused with all this......!!??!!
It's well worth the effort I reckon, 'cause when you're done, your shoes will have surfaces that are so thin they are almost transparent. A lot thinner than modded Lavers!!
Like I said, I've only had mine for about a month, so I wouldn't yet be able to say anything about the quality or durability of them. But they seem promising.....
That's it from here. Hope it works.
