Vivobarefoot - Primus Trail Knit FG

I have 8 pairs of vivos and have been a Barefoot shoe guy for 15+ years. Here's my two cents.  I love the knit shoes for everyday wear. They look so dang nice. However, they're noticebly narrower in the toe box. Something to keep in mind if you care about that.  Like others have said, the primus lites are thinner soles. I don't run so much, but walk and hike a ton. On longer outings it's nice to have slightly thicker soles. Probably would be even more so in a half marathon.  I know vivo recently came out with a running specific shoe. ive been considering getting more into running and have had my eye on those. Might be worth checking out.  For trails I alternate between the sandals and boots depending on the weather. Before getting those I used the Primus trail knit and they were also great. If I get a new pair then I'd get the regular version for the wider toe box.  I've had my eye on the hydras, but those seem like very specific use case shoes. I don't go in the water enough to justify getting.  I've also had my eye on the gym shoes they make, but I've been content using my oldest pair of Primus lites for working out. I do strength training 4 days a week. 

barefoot shoe user for approx 20 yrs. mainly vivo and fivefingers but also altra, topo, merrell, skinners etc. Always come back for the trail FG. A true swiss army knife. Use in the city but also for running on gravel road and even hiking. For me the primus can be a bit thin for longer walks in the city and the SG sole a bit soft for hiking when rocky. good luck!

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.

just back from a week in Norway. Late spring with more snow melting than normal. As such rather wet and muddy, your leather boots will never dry over night if you do not stay in huts that has a warm "dry room", something not all huts has. The FG might be slippery, the SG sole would be better but with sharp rocks I find it to soft. Altra Lone Peak or similar is something to consider. Of the two you asked about I would go for the FG but no need for allweather as mud and water will enter the shoe anyway, even with gaiters. I rotate merino socks, toe-socks, and Seal Skinz socks. Enjoy!

I just picked up the Primus Trail Knit FG and am really liking them so far. Great grip and they seem to hold up in all types of terrain.

Primus trail knit is my favorite vivo I've tried. They're the widest ive tried for sure. Just got the Chelsea boot today though and those are feeling pretty wide off the bat.

I used them a lot, but it's true that they squeeze the foot quite a bit. As time went by they bothered me a little more for that reason. Otherwise, I didn't have any problems.

I wear Merrell Vapor Gloves and Earthrunner sandals daily and hike in Vivo Primus Trail FG Knit. The most I've done in Vivos is a day hike in the White Mountains but wore extra weight in the pack. I was planning on the Vivos for my JMT this September (possibly alternating with the Earthrunners) but so many here would choose otherwise that I'm now questioning it. But, when my feet are in ANY other shoes (aka feet prison), they literally scream for freedom. My gut says the Vivos are the right choice but I will continue to deliberate.

Vivobarefoot Primus Trail Knit are ELITE

Has their last for the Primus FG narrowed recently? Mine are a couple of years old now and already feel bit on the narrow side.

Guess it depends. I've used the following minimalist trail shoes so far: * Merrell Vapor Glove 1, 4, and 5 * Xero Scrambler Low * Vivo Primus Trail Knit FG I also recently bought the Vivo Primus Trail Flow, but I haven't been able to take them out on a trail run yet. I will be taking them on trail runs in Spain next month, and I'm planning on doing a review of them afterwards. Anyways, out of the shoes that I've tried: * The most fun: The Vapor Gloves are incredibly fun due to their low stack height, but you need to be much more mindful of where you step. They also don't have any lugs and only treads, so they are only really usable in non-technical, solid ground terrain. I love the 5th gen for everyday wear, but for trail running, the 1st and 4th gen are more enjoyable because they are more flexible. * The most comfortable: The Primus Trail Knit FGs are so incredibly comfortable, and I've done a 50K trail race and a self-supported 64K trail run in them. The knit material means that your foot will slide inside the shoe when moving laterally, so they are best suited for non-technical trails. The knit material also soaks up moisture, so they get super heavy (and they are already quite heavy at 400g) when wet. * The lightest: The Vivo Primus Trail Flow is only 219g, and while I don't know if they're the lightest minimalist trail runners of all time, they are incredibly light. For reference, the Trail Glove 7 is 239g, and the Mesa Trail IIs are 221g, and both are some of the lightest minimalist trail runners in the market. The Freet Calver is a whopping 526g. While untested in the trails, I love the treads of the outsoles, and I'm looking forward to seeing how the lightweight trail runners fare in the trails.

I've been running in minimalist shoes for over a decade, and I love them. My feet and calves are very used to shoes with minimal cushions after a decade in them, but they do require some unlearning of shod habits to wear injury-free. Minimalist shoes pack down super well, are ultralight, and will do wonders for your feet and calves. If I had to pick a single shoe, I love my [Vivobarefoot Primus Lite Knit](https://www.vivobarefoot.com/us/primus-lite-knit-training-footwear) in black, which doesn't look out of place in everyday situations while being a fantastic shoe for exercise. As a trail runner, the other minimalist shoes I wear are: * Vivobarefoot Primus Trail Knit * Xero Scrambler Low * Xero Z-Trail EV * Merrell Vapor Glove

These are still my favorite Vivobarefoot shoes. I wear them all year round (if it’s not raining all day). I have narrow feet, so no problem with them
