Personally don't find much difference in the breathability of each, but do find that the all weathers are a little wider and more comfortable (for me)

I think you'll actually like all 3. I have the grey trail knit and they're my all time favorite vivo shoe.

I have a low volume foot and I like the fit on the trail knit. They hug my foot like a nice stretchy sock. I think you'll prefer that. The FG is good, but a little loose and stiff. I really like the ora for the reasons you stated. Its nice getting my feet wet, but I did kick a rock once and that made me sad. Now I'm more hesitant to wear them

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.

Yep, about my experience, not tried the all weathers but the knits are a little on the slimmer side compared to my lites and motus

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.

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.

Are you running or walking when you get feet pain on concrete with the Vapor Glove 7s? I use the Vapor Glove 5s as my daily shoe and have used the 1st, 4th, and 5th gens of the Vapor Gloves as my daily shoes + backup running shoes for both road and trail, and I don't have any issues. But I have been using minimalist shoes for over a decade now, so maybe that's why. Maybe you need to train your feet and calf muscles, or practice your landing positioning and form? > The most important: there are some shoes in the middle between Trail Glove and Vapor Glove? I love trail running in my Vapor Gloves, but I only use them for shorter trail runs less than 10K, since I really need to be careful about where and how I land. For longer trail runs, I use Vivobarefoot Primus Trail Flows and Primus Trail FGs. I love the Trail Flows for rocky, technical terrain and the Trail FGs for non-technical, dirt trails (as the name Firm Ground insinuates).

> And so you are saiyng that the trail collection from Vivo is more protective? The Vivo trail runners have a higher stack height than the Vapor Gloves. I went on trail runs up to 63K in my Vivo Primus Trail Knits, and I'll be running a 112K ultra trail in my Vivo Primus Trail FG 3.5s. The Vivos should treat you well, provided your feet shape is compatible with Vivo's aggressive toebox tapering.
