I have True Knit 2.0, True Lux Sport and True OG Sport (I pre-ordered True Lux Sport in 2 colors and they sent an OG Sport, and they offered to pay the return shipping and send the proper pair but I ended up liking them so they gave me $25 coupon and the $10 difference). True Knit 2.0 are definitely the most… malleable knit of the lot. Meaning they get a bit more stretched out/loose, which if you have very wide feet may not be an issue as you’ll have the ability to tighten them, but I have a fairly narrow mid-foot and found the lacing closure system difficult to get tight enough in that region after 2 months of pretty solid wear of both walking rounds and practicing, and you can see the difference between it and the sport style lacing on the images. True Lux Sport and True OG Sport run a bit higher on the foot (Lux maybe a touch higher), but not above the ankle. If you’ve played any cleat sports and work the above ankle pairs, it isn’t like those (I disliked those) and it comes to below the ankle, but just a bit higher than your usual shoe. I really like it, I’ve always hated shoes where the back in the heel feels a bit low/cut off, and it isn’t restrictive at all. True Lux Sport (and Knit 2) is the transitional drop, True OG Sport is minimal. 4mm is pretty mild, but the difference is noticeable. I’ll speak on only the sport style from here as I haven’t worn my Knit 2, and I genuinely do believe both of the sport pairs are better than the Knit 2s, the lacing system is just superior regardless of foot style or shape and the knit seems as if it holds up better (I haven’t noticed any of the issue of it being too malleable on either that I had with the Knit 2). True Lux Sport the toebox is smaller than the OG Sport. It is noticeable, but I wouldn’t classify it as small either. I wear Vivo’s often/nearly full time (barefoot shoes with a wide toebox) and my toes are pretty spread, and I don’t get any restriction on either, but the OG Sport definitely is wider. Midfoot is roughly the same and both can be adjusted as needed in that area, I can get them narrow there but they don’t start narrow feeling there at default (which you can loosen up), so I’d say you’re safe regardless of foot shape. As noted the drop is noticeable, OG Sport definitely feels more like a barefoot shoe but the drop in the transitional is slightly less than the drop was in my Adidas Boost (the knit ones, it was ages ago and I forget the name of them, they had spikes) and a bit more than that when comparing to my Nike 270G. The other notable, in fact I’d say probably the most notable aspect, is the rigidity of the sole itself. The Lux Sport is the firmest, flexible enough that it is very comfortable to walk wearing them but definitely firmer than the OG Sport, which are very flexible and really do feel very much like a barefoot shoe as a result. Very comfortable as well, probably slightly more comfortable but that would vary depending on your preference/needs in that realm. The Knit 2 fall somewhere in the middle of those 2 in that realm. In regards to walking, OG Sport edges it (barely, it could easily flip entirely for someone else) for me as I’m used to a flexible sole and find it comfortable. However if you aren’t used to a very flexible sole you may find these give you a bit of soreness on the bottom of your foot initially, especially if your posterior chain mobility (especially calves) is tight and puts even more strain on the plantar fascia on the bottom of your foot as a result. In regards to hitting the ball, I prefer the firmer feeling of the sole of the Lux Sport. Again mild but probably less mild than the difference in walking comfort, since these are the ones I wear the most. Your mileage will vary here too depending on your preferences, but I played football (soccer) for years and all of my athletic stuff always occurred in a boot (cleat) that had a very rigid sole (carbonfibre in lots of them, so very, very little give at all), and I like the feeling of that rigidity when swinging. That said when doing speed training I’ve worn both pairs and it has always come out the same, so it really is just going to be a preference thing there. Regarding the wanderlux insole, it is just a nice, high quality insole. Nothing fancy, just comfortable. The Adidas Boost shoes I wore I remember having an almost springy feeling when walking from the middle of the shoe which was where their boost technology was. It wasn’t anything to do with the insole (I wore out that insole fast), just the shoe. You won’t get that ‘spring’ with any of these, but they are super comfortable and very easy to walk in and honestly I prefer any of them to walk in over any other golf shoe I’ve worn. The only thing I’d note about them is that they are spikeless and don’t feel like they’ll have any slippage on anything damp, but once the ground got to where it was sometimes a bit softer/muddier, I had the odd shot often enough where I didn’t love the traction and I bought a pair of spiked shoes, but even though the spiked shoes are comfortable I really find myself trying to push it to not wear them as they aren’t nearly as comfortable feeling as the True’s. The OG Sport are definitely the best gripwise, bottom of the sole is different and has more grip and I can get away with those in the muddier conditions. I’ll note on the above that I have a bit of a flying left foot (left foot does a bit of a rainbow movement, think a much less exaggerated version of the long drive guys and more along the lines of how much you’d see on the fast guys on the PGA Tour, just without the ball going nearly as close to where I aimed it…) on anything 7iron to driver (SS 120 on course currently) and driver was where I felt a bit too little traction, so if you don’t move your feet at all or notice any real ground damage/scuffage after you swing from your feet pushing into it, I doubt you’ll have any issue in almost any weather that spikes would fix.
