    Der Dau Boot Stretch is rated 4.7 out of 5 by 44.
    Rated 5 out of 5 by from Really works!! I'm in between the slim and regular sizes for Ariat's tall boots so I bought this instead going the "two pairs of tall socks and a hair dryer" method for stretching out my boots. And it's crazy how well and fast it worked!
    Date published: 2016-05-14
    Rated 5 out of 5 by from Worked great! I have a pair of chaps that had spent years as my back up and were so stiff and dry. After conditioning them, they still felt too stiff and were too tight. I was about to give up but ordered this instead. This boot stretch worked perfect and the chaps fit great now! I would recommend to anyone with boots or chaps that are just a little too tight or stiff.

    Rated 5 out of 5 by from Amazed I got this boot spray last week because I bought brand new wide calf Ariat's that I just couldn't get zipped up. I have pretty wide calfs that have been getting smaller but are still wider than the typical "wide" boot. Anyways.. After one application to my left boot- I could zip it all the way up. I have done two applications to my right boot and it is so close that I feel after another application or two, it should zip all the way up! I am so very pleased I gave this product a try- and it was because of the reviews that I even decided to order it, so I figured I would share my review for others that may be trying to decide. I didn't want to take brand new boots in to be altered, and this product made it so that I didn't have to!

    Rated 5 out of 5 by from It worked! After a couple of applications, the boots that I had planned to sell can now be ridden in! I sprayed both the inside and outside of the boot where I wanted it to stretch, and reapplied about 10 minutes later when the first application had been soaked up by the leather.

    Rated 5 out of 5 by from Good Stuff! This stuff really does work to stretch boots enough to get them on. My boots were so tight in the ankle I almost crushed the heel cap getting them on. Now they go on easily even though I have to use the spray every time. Now that I have used half of the bottle, one of the boots goes on with no spray. I hope that soon they both will.

    Rated 5 out of 5 by from Impressed I bought this for a pair of show tall boots I have. Before when I zipped them up I would lose all feeling in my feet. I was a little skeptical of this product but I gave it a try and it really works. I can walk around all day with my boots on now.

    Rated 4 out of 5 by from Great product to have around I have purchased two bottles of this product over the last year or so and it works well. One thing I have noticed is that if your boots get wet and you let them air dry they will shrink and you will have to apply the Boot Stretch again. Not a big issue as this product is reasonably priced and it goes a long ways. It worked great on a pair of Ovation Gold tall boots I purchased nearly 10 years ago, but does not seem to work as well on my new Ariat's.

    Rated 1 out of 5 by from Not much change I used this product on Ariat Quantum Crowne Pro Field Boots and didn't notice a significant amount of stretch in the calf.
    Date published: 2014-08-19
    Rated 5 out of 5 by from Great Product and Great Service I bought a pair of boots to fit my large calves. The young woman in the store was excellent. She talked me out of a pair I thought fit, helped me select the right size, and told me the boot stretcher would work to make them fit well. When I received them I thought OMG these will never fit. But the boot stretcher works like a charm and I have a pair of tall boots that look like they were made for me! Couldn't be happier.

    Rated 5 out of 5 by from It actually works!! Like some others have said, I was pretty skeptical of this product, despite the great reviews, but I ordered it out of desperation. My $400 ariat show boots (an extreme splurge for my family to buy), were way too tight, but only four years old, so I sure wasn't going to replace them! At a clinic last week, after about a minute of having them on, pain was shooting down my calf, and I actually had to ride with one half way unzipped! I put this on the inside calf for the first time yesterday and walked around for a while, and was limping by the end of the process. Today I put the boots back on, and there was absolutely no pain!! Not at all! They're still pretty snug, but I can actually fully use my lower leg now. I plan to do a third application tomorrow to get it just a bit looser. So thrilled this worked!

    Rated 3 out of 5 by from Works well Used it on the clad of a new pair of DeNiros and it stretched them a little but. Not as much I I needed them to stretch though. I had to put the spray then oil. Then I heated it up with a hair dryer and wore them till they cooled.
    Date published: 2014-07-14
    Rated 5 out of 5 by from Great Product I bought some very expensive custom boots last spring and was very disappointed when I could barley zip them up. Even after I got them zipped up my foot would fall asleep (not very helpful when riding). I applied this product two times and my boots now fit perfectly. This product is awesome and has a great price. I would encourage anyone with boots that are too tight to try this product first before buying new boots or expensive alterations.
    Date published: 2014-05-27
    Rated 5 out of 5 by from AMAZING!! I can't believe how well this worked! I bought some very expensive boots second hand but I couldn't get them on over my calves. Literally minutes after applying this spray I was fitting into my boots. More spraying and they got more and more comfortable. Thank you for carrying this product! Attached is a pic about half an hour after application.

    Rated 5 out of 5 by from It really works! I inherited several pairs of custom field boots that needed real TLC. I tried the Der Dau bootstretch to soften them up and give them some flexibility--it gave the boots the stretch and liability I needed!
    Date published: 2014-05-05
    Rated 5 out of 5 by from Works! Used this spray on some very narrow calf Ariat boots with the stretcher. Really helped loosen the leather.
    Date published: 2014-04-18
    Rated 5 out of 5 by from All you need is one application! I recently purchased La Mundial customs... I was extremely disappointed to discover the left calf to be significantly smaller then the right one. I read the reviews of this product and decided to give it a try! One application (a few sprays) on the inside of the calf and the boots fit perfectly (and I can feel my toes now). I will admit I was a bit skeptical of this product even though the reviews were wonderful. However, I am VERY happy I purchased this product and recommend it to anyone with tight boots :-)
    Date published: 2014-03-04
    Rated 5 out of 5 by from saved my boots for me I broke my ankle and that leg was too big for my De Niros, which had fit me like custom boots. The Der Dau Boot Stretch worked like a charm. I had even taken the boots to a repair shop to have them stretched. The pro failed. The Der Dau did not!
    Date published: 2014-02-12
    Rated 4 out of 5 by from Good product I bought this because a set of closures on a pair of boots was a touch too short to snap up when the boots were on. This helped the closure tab stretch just enough so that I could get it closed. It's a good deal for the money because it only takes a little bit of the spray to work.
    Date published: 2014-01-12
    Rated 5 out of 5 by from Must have for boot owners!!! A pair of my zip up tall boots tend to be too tight to zip after I've been on my feet all day. I spray the boot stretch spray, and then I'm able to zip them up all the way. this is a must have for ALL boot owners!
    Date published: 2013-12-15
    Rated 5 out of 5 by from FANTASTIC!! This product was remarkable. It saved me $300 on a new pair of boots. My daughter had a growth spurt and, while the feet have not yet caught up, she had trouble zipping her barely used, 6 month old boots. We sprayed this on them, she wore them around the barn one Saturday and voila, a custom fit.

    Rated 5 out of 5 by from Total Money Saver This Christmas I ordered a pair of patent top semi-custom DeNiros. I have a small calf, however I am also runner and consequently have very pronounced calf muscles. Thus, when I got my boots this spring they were so tight that I could barely zip them up. I thought that I would have to eat the $900 dollars I put into them until I read the reviews about this product and decided to give it a try! It worked wonders! In about 3 applications my boots were fully broken in at the ankles and the product allowed the calf area to stretch and mold to my leg. They are now the most comfortable boots I've ever ridden in (I've ridden in Ariats for the last 8+ years), and they also look completely custom!
    Date published: 2013-07-11
    Rated 4 out of 5 by from Works Well I actually got this to use on several leather high heals in an effort to make them more comfortable. It did the job! You have to commit to spraying and walking until the leather is dry.
    Date published: 2013-04-02
    Rated 5 out of 5 by from Works Had Petrie boots that were killing my legs after months of attempting to break them in. Finally tried this product... and viola! No more blisters!! Only had to use two applications. Recommend to anyone buying a stiff dressage boot!

    Rated 5 out of 5 by from Der Dau boot stretch Pretty good stuff - didn't need it on all parts of my boots, just the top - seemed to work pretty well.
    Date published: 2013-02-07
    Rated 5 out of 5 by from This stuff works! I bought this for my husband to try to salvage a pair of expensive work boots that were a tad too narrow. So far, he's used it a number of times and is seeing results. Better than wasting $100!
    Date published: 2013-01-26
    Rated 5 out of 5 by from It works!!!! I recently pulled out my pair of Ariat field boots that had been sitting in their box for quite a while. I couldn't get the zippers up, so after reading some reviews, I decided to try Der Dau boot stretch spray. It works! I did have to spray the boots and then get them zipped up & wear them for a while, and I did have to do this several times. I definitely recommend this product!
    Date published: 2013-01-09
    Rated 5 out of 5 by from Actually Works I got a pair of tall boots on clearance that were .5" short of what I measured for, but figured they were worth the chance. With the help of this boot spray and some old fashioned exercise, they fit with no problem! The spray helped my boots from being unable to zip up fully with thick breeches, to a snug but comfortable fit with any riding attire. Major win!
    Date published: 2012-10-29
    Rated 5 out of 5 by from Really works and so easy! This is a great product. I wish I had found it when I first started breaking in my Dressage boots. I used lambswool padding on my ankles for months and after using this spray twice, my boot are comfortable with just socks.
    Date published: 2012-10-02
    Rated 5 out of 5 by from Works great This works great. I noticed a difference on the first application!
    Date published: 2012-06-13
    Rated 5 out of 5 by from Wow! I had gotten a real deal on a barely used pair of Ariat Monacos and I was so excited! The only thing was that they were cutting off the circulation in my feet and it took me over 10 minutes just to zip one boot, getting a nasty blister on my finger. On the next boot I broke the zipper pull off! I was desperate to make these fit so I took a warm bath in them and wore them until they dried (over my socks and breeches) then a couple days later used this spray. after spraying once and walking around, I could zip them up without assistance. after the second spray I could zip them easily and they look and feel custom! I only used about half the bottle so I plan on using this to break in the schooling boots I just bought. Amazing, boot-saving product!
