I am often presented with holes in shoes like this, usually by people with toes bleeding or whatever, but the answer is always the same and in two parts.
The first part is yes shoes can always be fixed easily enough, the most common product is Shoe Goo, which is usually available from most skate shops and online via ebay, in most countries too, or a similar variation of it. Failing that, some cheap normal super glue, available almost anywhere can also help, if you cannot get Shoe Goo.
The second part is more for next time, to try to sort out your shoe before it gets to this stage. A little super glue on stitches or joins of high wear areas before you skate in them will help with a lot of the coming apart problems, but also some Shoe Goo over the hole or area that is wearing down before you go right through it.
If you have canvas side in high wear areas, such as Vans Old Skool or on these Lakai shoes, you most definitely need to hit that with something, because one decent session in a brand new pair of these and you will be right through the side of the shoe, most likely through your sock and maybe even enough skin to make you need medical attention.
