Frequently Asked Questions
Are these boots waterproof?

The Primary Low is 10 inches tall, making it shorter than a traditional Engineer for riders who prefer a lower profile.
What's the warranty coverage?

Impressive
I was looking for an option to the $300 Harley boot when I found this one. The boot is vey comfortable, and has help up in the weather. I have had it rain twice with no issues. The boot is a tide wide for me but that would not prevent me from purchasing another pair. The boot also had a very short break in period.

Wide at the top
The boots look great, but they are so wide at the top that it doesn't look good with pants over them. They're similar to a rubber rain boot in how wide they are at the top. I saw other reviews mention they are sized accurately but I personally found them to be both too narrow and too small.

Decent boot, but wide ankle
I bought these for my husband and they were decently made, but the ankle was far to wide and looked funny when tucked under pants.

Perfect, but can be improved.
These were the only engineer-styled boots that are waterproof and do not have those shifter panels that give it away that it is a motorcycle boots. However, I do have some gripes with it. Firstly, I think the fit is a little loose. I'm a 41 euro and the gear geeks told me to size up with the US9. The first time wearing them felt almost snug, easy to get in. After a few times wearing these (with a really short period to break in), they are looser now and extremely easy to get in. If I were to buy them again, maybe I'd try the size 8? Secondly, the cut of the boot makes it much more geared towards wearing the boot over my pants. However, I'd prefer to wear it under my pants like Brando does. I can do it, but the mouth of the boot is pretty big, pushing out the hem of my pants wide open. Lastly, the straps are mostly ornamental than functional. I think I will be punching more holes to cinch them tighter. Waterproofing-wise, they are 100% no doubt about it. Nonetheless, I'd say I'm pretty much satisfied with these.

Excellent boot
The fit is a bit loose but nonetheless really comfortable. Easy to take on and off, slick style and they look really durable. I recommend these.

My one and only pair
these are my go to boots, super comfortable. I ride in them all year long and they do ok off the bike as well, Ill definitely get another pair but after several years these boots are still going strong. These are not technical boots but its leather and I feel like for my style of riding (sport tourer they) are perfect.
