The quality on this boot is great. The comfort is great. The only issue I have with this boot is that even though it does give you an extra few inches (for short riders), the difference does not translate into flat footing if you are on a sport bike. I have a inseam of only 29 and saw all of the great reviews about how this boot helps with short riders, so I bought these boots for that soul purpose. I didn't want to drop my new Ducati 899 at a stop if you know what i mean, so I wanted extra insurance. Well to my surprise, the boot did make me taller while standing up it did not help with flat footing my Ducati 899. However, the quality and comfort of these boots made up for it. So just a little warning for those short riders trying to get a little insurance, this boot might not do the job.

The sole is firm, but there is a flex point at the ball of the foot for walking around. I wouldn't walk too far, but they would function well for both standing on foot pegs, and stopping somewhere to stretch in a small town. I would not recommend them for more than very short "hikes" off the bike over uneven terrain due to minimal flex in the sole. The sole does have good grip, and the bit of extra height is a nice addition, although the boots are a bit heavier because of this, and take a bit of getting used to.
These have a fantastically, ergonomically comfortable footbed with good moderate arch support, however, they do run a bit longer in inner length than any other boots I've had in the same european size (41). The footbed is just wide enough to accommodate my wide foot, a narrow foot might slide around. If I had wanted to wait for an exchange, I actually would have gone down from my 41 to a 40, even though I have a wide foot (I wear a woman's 8.5, and choose wide width in other shoes whenever available). But with thick socks, they are manageable.
The adjustable calf area allows for a wide range of calf sizes, yet the inner gaiter fits snug and soft around your leg, so no cold breezes up the pants. There are no pinch points or 'friction spots' on the shin for me. The toe bed is tall enough inside for thick socks or inserts, however, I will have to adjust my shift lever up just a small bit, although not extreme.
The outside has two zippers. The zipper on the outer side of the leg runs about half-way down the foot bed and allows for easy off and on, however, I find it awkward to unzip the boot on the outside of the leg. I do use it though, because the zipper on the inner leg only goes to the top of the anklebone, and there is no way I can get my foot out using only the inner zipper. I do wish they were reversed, but it is functional.
Overall, they appear to have all of the features I was looking for in a long term boot, I have not had them in a downpour, but they are Goretex guaranteed, and I've properly treated the leather with the recommended product before wearing the first time. At this price point, I am sure to give them the best care, and expect many years in return. I found many pictures of these boots, well-used, posted by owners who loved these boots, and that gave me peace of mind. They seem to have held up well for others.

As a few previous reviewers had mentioned I also had trouble zipping up the curved zipper. I attached a cable tie through the hole in the zipper pull and pull up on that rather than the zipper itself. This seems to make zipping the boot much easier.

Great boot that I hope to have for many years.

So this is the famous Daytona M-Star boot, famous because it probably adds more reach to the ground (i.e., lift) than any other boot on the market. I went from balls of my feet to flat footing my VFR800, for instance.

But that great benefit aside, this boot is incredibly well made. Very high quality materials, very flexible fitment, very solid feel. The first 6 or so times I put it on it was a real struggle to get the full zipper up but eventually the leather loosened up enough so that it wasn't such a chore. In my mind that's a reflection of how securely this boot fits after break-in.

I haven't had the opportunity to test the watertightness of this boot, but I've worn it in 100+ degree heat and had no unusual discomfort. This boot will do it all.

I fully expect to keep this boot for years, and will resole it if I need to. I can't say the same thing about the Dainese Nighthawk boot this replaced, which isn't half the quality even though it was more than half the price. That's not a knock on Dainese, that's just how good the Daytona boot really is.

This is a great all-around riding boot. It also adds a little lift for midget riders like me.
Totally recommend.

I purchased the M Star to flat-foot my BMW S1000XR. The boot helped quite a bit on that score. The boot is also very comfortable, well made, etc.

My one concern is that the boot toe is bulky for shifting. My left foot gets stuck when I try to fit it under the shift lever for upshifting. Haven't yet tried to adjust the lever or seek out after-market levers, so we'll see. I'm keeping the boots because I need these extra inches for flat-footing, stability, etc. Hard to believe that I'm the only person noticing this, but who knows?

As one reviewer said - this is a motorcycle boot. It is storm trooper style. That having been said - it is a great boot. Great protection (not for the track), excellent leather build and craftsmanship, warm and water proof. Another reviewer said it's not too hot in warm weather - that's subjective. I live in the Austin Texas area and if it's above 80 degrees my feet will sweat in these (they are gortex). The boot sole is stiff so walking in these for any length of time would not be a great idea. They are comfortable though for short walks but not walking for several blocks (say more than 1/4 mile). I found the fit spot on - look at the sizing guide. Airflow - well they are not summer boots.

Gr8 Boots. The more you use them, the better they feel. They could seem expensive at the moment you place the order, but once your reach is increased, they are Priceless!! Off course any saving is a good saving.

You have to adjust your Shift Gear + Rear Brake foot levers. Other than that, they are OK. The Boots are not the prettiest, but that, is out of the equation; their main Feature is the increase of reach. Another good feature are the two zippers system for your feet's easy in/out.

It took 3 or 4 rides for the boots to zip open and closed easily. They are extremely comfortable. I replaced the inner foot pad as I did not need the height adjustment pad. Only issue is shifting due to the thickness of the boot. I ride a 2012 Goldwing with a toe shifter and needed to adjust my riding foot position to accommodate the difference....but, love the boot.

Very expensive, but I think I nailed them! They add almost 3 inches (I am about 5´9") and now I can reach flatfoot with my 2 feet much easier on my BMW K1600GTLE. On top of that the boot feels great, the craftsmanship is amazing and the stitch details and built are fantastic!! Couldn't´t be happier.
If you can afford them I highly recommend you buy from Daytona. You will not regret it
