r/vivobarefootLong term Vivo wearer here (8 years+) and i think I'm done. Where do i go from here?

I've got the same FG3.5 and was concerned about my size being one two big. But after a week in the mountain I think I picked the right one. They just seem so different from my Primus Lite that its hard to compare. The primus lite are probably my favorite shoes I've ever had at this point. But sad the sole is getting worn out after a year.

have had both, currently the knit, find the knit a bit heavy and less "good looking" but very easy to put on. I would buy the regular and put on stretch laces. as the lawyers say, there is a specialist for every opinion.

r/vivobarefootFirst pair of Vivos for digital nomad life – Primus Trail FG 3.5 vs Primus Trail Flow vs Tracker AT Low?

Get black primus trail 3.5. They’ll do most scenarios. People that bitch about the laces need to get a grip. Cut them if they’re too long.

Kinda side-stepping your convo, but how do you like the Primus Trail Knit? I have a pair of the Primus Trail FG 3.5, but still within the 100 day trial and definitely ordered a size too small

I mainly hike with [barefoot](https://vivobarefoot.com.au/collections/mens/products/primus-trail-fg-3-5-mens-dark-shadow?variant=46345330163929) trail runners and have never looked back.

r/discgolfBest Disc Golf Shoes??

Yup. I have Primus lite 3’s, and the Primus trail 3’s and love them both. Probably wear the lite 3’s the most though because they’re great with concrete and the trails are better for turf. I myself like less tread on concrete pads as the trail tread is almost too grippy for that.

Lite III and Trail FG is all you need. (Except during winter and snow. I have had near frost damage situations because of using Vivos in sub-zero Celsius temps, so in winter i use «normal» winter shoes.)

r/trailrunningWhat are your best mud-running tips? And shoe recs?

Same shoes and socks all year. Vivo barefoot Primus Trail FG (firm ground) not the SG (soft ground). Thin wool blend aocks. Maybe some gators if it's a long run. Try to avoid the puddles for a few minutes until you fully dunk your foot. Then say fuck it and just got straight thru the puddles. If you want to stay clean and dry, stay inside.

Plus one for the Primus Trail FG - best low-profile trail running shoe by far and a great all-rounder for travel adventures - may be too sporty/rugged for nice dinners but meets everything else. Anything barefoot style will keep it low profile. I'd pair vivo's and whitin's canvas shoes for my offroad/hiking needs vs my city walking/more dressy occassions.

r/onebagWhat's your go-to, go anywhere footwear?

VivoBarefoot Primus Trail FG. Have been wearing them exclusively, aside from my sandals, for two years of traveling. They are still usable but at the point that it makes sense to instead leave them as gym shoes or something and bring a new pair on my next travels.
