    Help find a new casual / business casual shoe

    All these designers that think a wide toebox is the thing are completely off the mark. A high toebox is what's important. And most err on the too-wide side making for a slippery shoe.

    Vivobarefoot Gobi

    Well these made it a little over a year of everyday use before a puncture created a small crack in the heel. They took quite a bit of punishment and the treads barely wore down. The crack has not extended but it appears irreparable as shoe goo would not take to the vivo rubber and simply peeled...

    I need materials

    That could be the right stuff. Yes it's expensive - if it's sole-worthy I wouldn't need a whole big sheet of it. They claim it is extremely flexible, is this true? I need flexibility but not a lot of elasticity. Also do you know anywhere to get the real barge cement, not the reformulation...

    I need materials

    I need super-thin but tough rubber to improve some devices I make to protect my skin from peeling when sprinting barefoot on a track or rough pavement. Currently I have a big sheet of 1/16" butyl rubber which results in serviceable but clunky skin-guards that tear apart after two or three...

    Vivobarefoot Gobi

    After more than 10 months I must grudgingly upgrade the durability score to 5. Regular heavy use on all kinds of abrasive surfaces including pavement and wildlands has barely even dented the treads. They are probably going to last another year at least. If all shoes were made with this rubber...

    This is what happens when you don't know how to run barefoot...

    It is not the heat, it's the stickiness of the track combined with the fast pace which makes it like sandpaper. I usually use spikes for speedwork but occasionally run a few repeats barefoot and always lose a bit of blood and skin. At road race paces there is far less friction, unless you're...

    it is dangerous to run/be barefoot at 7º?

    I got frostbite from a 15 minute run in 9f, though there was snow on the ground which makes a biiiig difference. Dry ground is much safer than wet. It was mild frostbite but the fluid oozed for days. In snow/ice I now wear track spikes

    Overdid it.

    You got a under-callous blister, AFAIK it's no big deal

    Meatheads get Hip on Barefoot Fitness

    old news. Arnold lifted barefoot.

    Barefoot Running may be hard for those over 30.

    There's not even any such thing as midfoot landing. Simultaneous forefoot-and-heel landing, but the arch doesn't land. Unless it's flat maybe.

    HPV Infections

    Are there really people scraping their fingers and/or genitals on the floor??? I'd be a lot more concerned about things people touch with their hands and/or genitals, such as a public toilet seat. You can dodge a lot of colds and flus by not touching light switches or door knobs with your...

    The Grass Illusion

    Have you ever run with your eyes closed? On, say, an open field where there's nothing to crash into, for a few seconds. If you try it (at your own liability, don't blame me if you knock someone over or run into a goalpost) you might be surprised how off kilter your awareness of the ground and...

    Vivobarefoot Gobi

    These shoes are now fully broken in. I am upgrading their durability to 5 - the treads are all mostly intact and the rubber is wearing very slowly. Unfortunately it has not softened much so the flexibility is as bad as my initial impression, as is the ground feel. The closest thing I can...

    what side does glass get you

    as far as I can recall, glass has nearly always got me on the right side, a few times total. I'm not sure why but I land differently on that side thanks to an ankle sprain long ago. Or maybe because I'm right handed.

    Vivobarefoot Gobi

    Edited to explain. No, they don't slip, the treads provide plenty of traction, part of the reason the sole is so stiff.

    Vivobarefoot Gobi

    These are my initial impressions of the Vivo Gobi which I bought as an everyday street shoe and have used a couple days. As they break in I will update this review. Ground Feel: 1 out of 5. Fails the wet pavement test - when I walk on wet pavement, it doesn't feel wet, which to me is the...

    5th Annual Winter Challenge

    The penalty for frostbite should be disqualification. It's not worth the risk.

    Breathe Slower Yet Run Faster? really...

    Learn to read. I was responding to a troll who used a straw-man argument. I said you'll never get enough oxygen through nose or belly breathing for maximal exercise, and he claimed I said the nose wasn't for breathing at all. Or maybe you think it was rude of me to contradict one of these...

    Breathe Slower Yet Run Faster? really...

    Cute, but you know full well what "nose breathing" means. Let's see you run 600 meters in, say, 1:45 or less breathing only through your nose. With video proof. Endless threads on fringe subjects only makes BFR look fringe too. I'm not gonna be nice about it.

    Startling People and Animals

    You will reach Ninja level 1 when you can sneak up on a feral cat. You have to pass within 3 meters and it can't notice you until you've already passed it. It can't be a fat or domestic cat, unless it's an outdoor, territorial type that wanders far from home and is acutely aware of its...
