I have the Nail hi-top boot that I picked up from a guy on ebay who wasn't wearing them enough for just $30. I wear 8.5 and these are a 9, and have massive headroom/clearance inside, so I wished they were 8.5. But still, I can walk in these and the footbed has massive cushioning that doesn't seem to lose it's cushioness/get flat. The sole is close to iron clad, with the sole pattern requiring lots of effort and years of use to wear down. The upper material is soft and comfortable too, but not providing the kind of protection you'd expect from a safety boot, so be careful where you wear these. I sometimes wear these to work as I work in the office section of a refinery. I have 10 pairs of shoes/boots right now and this is into rotation.

The lace system on this shoe is unconventional, as the top 3-4 lace rungs (not eyelets) allow you to "hook" the laces around them. They don't come off, and I guess are smart in the sense that you don't feel the laces on the inside of the boot where it travels up your foot. Great ankle support, and relatively heavy/weighty too. This is a great and comfortable Timberland/Caterpillar-esque all terrain trekking boot.

The only cons about the Nail hi-top is the traction (which isn't totally great- eg: even BRS 1000 on Nike runners beats it for grippiness) and the extra space they have inside (runs large). Also protection from (let's say a "Nail" touch wood, haha, accidentally dropping on the Nail would only be passable at least). I guess it's not a safety boot, but I kinda expected something close, with it's name. 4 and 1/2 stars for the comfort and wearability.

Like all the Nail series these have a heavy sole, great padding, and good ankle support.

These are the coolest boots in my opinion even over the SI boot

These are a great everyday work shoe. They are very durable and stand up to the elements of the winter cold to the summer heat. I've had mine for 4 years now and I finally wore a hole in the side of the shoe. They are still very comfortable after all this time. Just a great shoe.

Color: Black, Yellow
Yep, comfy, good solid shoes, depending on the color combo, can look abit like spaz shoes..

Color: Olive Green / Yellow
I bought 2 pairs of Nails over the course of 2 years. The first pair was the Olive Green, I bought the yellow awhile later as they were on sale. Even though I pretty much hated the yellow colour I knew the boots were awesome and could find a use for them.

Would wear them often, until I got the S.I. boots that is.
