“Beefing Up” a FiveFingers for Off Trail Expeditions.

Why bother? The product works or it doesn't. Without the right glues and materials I would expect them to self destruct— shoes take a lot of stress.

I appreciate what you are trying to do, but for all the time and trouble and the propensity for a mini-disaster, I would pick a strong, lightweight hiking shoe and have a good hike. Your five fingers will be there for trail hiking.

I agree with Dale. Adding ankle support to Fivefingers seems to suggest that they're the wrong tool, especially.

Thinlight is the least durable foam I've seen. It would get shredded in moments.

IF you want ankle support (which i think is unnecessary) go for a light pair of boots, like the inov8 roclite’s at 13.5 grams Roclite 390GTX, almost the same weight as the five fingers.

Or just go for the five fingers as they are, people do huge distances barefoot or in hurrachas

I don't know about 'almost the same weight'. My KSO FiveFingers are 299g for a pair and my RocLite 390GTX's are 735g…150% heavier. The treks are likely heavier than the KSO's but they can't be anywhere near the 390's.

I wouldn't use FiveFingers for off-trail travel. Even on trail I have a hard enough time not stubbing my pinky toe every 5 minutes.

6. Any flaws you see in this setup?

It's a bit like converting a Smartcar into a monster truck, which is cool in a ridiculous kind of way, but not the best means to an end.

Since you're actually trying to improve the abrasion resistance of the exterior with nonbreathable foam, you might as well make the switch to leather. Check out the Inov-8 Roclite 400 GTX.

Treksports are listed at 13oz a pair. Is that rocklite number per shoe?

Yes, Roclite is per shoe. I believe that's the standard way of doing it.

"Thinlight is the least durable foam I've seen. It would get shredded in moments."

Agreed, it also loses its cushioning almost immediately if you compress it. I had some strapped to the outside of my pack for one day and it now has permanent strap marks.

One warning, if your feet aren't already strong, a long trip will hurt. I did a 3 day, 30 mile in a pair of FF KSOs and my feet hurt a lot. By the third day it was tolerable, but not comfortable by any means. I also found myself looking at the ground constantly so I didn't step on even small rocks, which can be very painful.

These are pretty light 212gm

I've used them up to 20 miles in a day on rugged trails.

The KSO Treks have more than sufficient front and bottom protection for a long hike –in my case anyway — much more than the KSO's. They really don't need any more top protection than the KSO's have already, IMO.

Walk around the neighborhood in them for several miles before you go.

Every foot on the planet requires a slightly different shoe configuration, however. For me the Inov8's have shoeboxes that are too small. They pinch my toes viciously.

I have never had a bit of trouble with the VFF's, however — certainly none of the ones described here. In fact, the VFF's solved all of my foot-related problems on the trail. I haven't even had a hot spot since I first put them on. I'd wear them to teach classes if I thought my students wouldn't laugh me right out of the classroom.

Is this a joke? All of that defeats the whole purpose of wearing a minimalist shoe…

I agree, this makes no sense to me at all.
This is like buying a superlight, frameless pack and then adding a frame and bulky hip belt.
You'd be much better off buying a product that is designed for what you need them to do. The Inov8's are a good example.

In fact, you can go even lighter if you don't care about waterproofness:
8.7 oz each, these are as light as it gets for a mid.

No comment.

I think your idea will actually weaken the shoes.

If you really want to try this (and why not? Trying things is fun), I suggest you buy materials from a cobbler supply. You could get some soling sheets or boot soles. Or else, consider purchasing some cheap flip-flops and using the soles. Perhaps if you can find some very thin ones you could cut them to fit your VFFs.

For glue, you should use Barge cement. It is what cobblers use. It holds very well.

I'm not certain why you'd need ankle support so much as maybe protection from abrasion. Consider just wearing gaiters or long pants instead of affixing some kind of brace.

Good luck on your project.

Injinji socks and gaiters.
I don't think that you would gain from anything else.
