Sierra Designs Classic Down Booties

2009-10-31 18:06:31

Reviewer:Marie N from Derry, New Hampshire

Overall Rating: (5 stars)

These are the only slippers I have ever found that keep my feet warm. Since I bought them a few weeks ago I have never again gone to bed with cold feet.\r\n\r\nA major criticism for me was the ankle strap. I have a sprained ankle and RSD and the strap was excruciating. I cut the strap from inside the slipper boot and now it is perfect. The strap seemed to make no difference in how warm the slipper would keep my feet.\r\n\r\nI wish Sierra would offer this product without the ankle strap but even with it it is a far superior slipper to any I have ever worn before. I wish I\'d had these slippers years ago - they would have saved me from warm foot soaks and "microwave" slippers and everything else I have tried to keep my feet warm. Thanks also to Zappos.com as I would not have found them without this website.

I was impressed with the speedy delivery of what I ordered. It seemed that no sooner had I pressed the send button on my computer, there were the boots at the door. Now That Is Service! The boots themselves were just what I needed to keep me warm in the house on our hardwood floors throughout the winter. two years ago, I got the less expensive sierra ones and altho they were utterly blissfully warm, the backside above the heels collapsed on me after a year, making them wrinkle uncomfortably under my heels. So much so that I needed to replace them this year even though they were not worn out yet. I hope this does not happen with my new ones. So although I gave the comfort and style 5 stars, I can not honestly rate them yet as to durability.

Bought as a gift for my husband. They fit well, are comfortable, great that they are washable. He is diabetic and wears them as bed socks, loves them!

Sierra Designs Makes One Cozy Toasty Down Bootie! I have an older pair of SD down booties and they're THE warmest slippers I own. I can think of only two "downsides" (no pun intended): 1. you can't just slip these things on and off like the average slipper, 2. the sole isn't very durable if you're going to wear them, say, to go grab the mail outside. We have a typical asphalt driveway, and the nylon sole began to wear and then rip after maybe a couple dozen brief trips outside. I didn't wear them on an errand to the store like a previous reviewer. If these had a more durable rubber/leather sole, that would make the price tag a lot easier to justify.

Great slippers for the house - I bought the medium (7-8) Biscayne boot for my wife, who is a 7 1/2. She says it fits perfectly and has worn it constantly since it came ONLY 16 HOURS after I ordered it with the free shipping. I highly recommend these Down Booties, and I think they look great, although you'd never see them on the runway in Paris. P.S. Zappos' customer service has won a new customer.

Reviewer:Anonymous from RVA

Warm - Pros: -Warm synthetic (cruelty free) down fill; add a thick pair of socks and the effect is doubled. These would be great for wearing inside of a sleeping bag, but I use them for a drafty apartment. -Slip on like socks and stay on reasonably well; I'm a size 11. I bought the XL (11.5-13)since my toes felt cramped in the L (10-11). My feet do slip around on the inside when moving quickly, but the ankles don't sag. -Rugged design; I expect these to last a long time. All of the materials are high strength, stitched to the hilt, and tear proof. The soles are made from a stiff fabric and I could conceive of heavy outdoor use tearing these up, but then, you should be wearing shoes instead if that were the case. -Lightweight; Ok, I don't backpack or care about material packing weights, but these are light and they scrunch up easily enough if need be. -Synthetic material; of the down filled booties I tried, some were warmer, but almost all of them had feather ends piercing the fabric which made them scratchy, stabby, and uncomfortable. This is not a problem with these synthetic filled booties. -Low key design; the design aesthetics, including the logo, are minimalistic. My gripe with most footwear is the lack of simple design. These are simple. Cons: -I would have liked more insulation. As warm as they are, a 700 fill equivalent would have been nice. -Inside stitching; The stitches connecting the sole to the rest of the booty form a stiff ridge around the foot and this can be uncomfortable. -No sliding; The materials grip stays while my foot leaves. -They swoosh. It's the material. If I lost these, I would probably look around for something with similar characteristics, the main difference being warmth and comfort in the 5 star range. These booties are solidly a 4 star for the price, fit, function, and design.

Warm and Comfy! I really needed something warm for my poor freezing feet! These shoes are totally not for fashion (but then again who would have thought Uggs were) but are great to run errands in or wear around the campground. So far they have stood up to small puddles and are very warm. They get a little wide on the sides of the feet after awhile and I have to wear socks bunched around my ankle to keep them from slipping down. Otherwise, they are great.

Finally!!!! WARM FEET - I have constantly cold feet due to peripheral neuropathy. These slipper boots are wonderful. I only have a slight issue with them, because they are so cushioned, the sole shifts when you walk in them, so be careful. Love Zappos, and the updated shipping. Thanks for warm, cozy feet!!!!!!!!

Overall this is a good product, however, I had bought a Sierra Boot and returned them because my dad could not get his foot in at the top. He had the SAME PROBLEM with the moccasins. The sole size was fine (Lg). They need to make the top opening larger... I will be returning the mocs.

Toasty toes - I always have cold feet, these did the trick, for the most part...I only wish the bottoms also had something to prevent slow cold seepage...if you keep your feet off the ground, it's not an issue.

Toasty! With a pair of warm socks, I have even worn these to the store! Just didn't want to take them off. They are a big and goofy-looking, but that also is because of the down needing space and I could care less. Love them.

Way Too Small - These slippers seemed to run very small. I would estimate at least two sizes smaller then what they are marked. I typically wear an 11 and I ordered the XL (fit sizes 11 to 13) and my heel was buried in the back of the slipper and my big toe was touching the front of the slipper. They also aren't very tall. They do not cover your ankle. Overall a very expensive slipper for what you are getting, IMO. I will have to look at a different pair to find something I like.

Warmth Plus! I always have cold feet and, though they make family members laugh because they are really big, these keep even my feet toasty. It's worth the kidding. The elastic at the ankle takes a little getting used to.

Stay warm - Excellent if you have cold feet or have come in from the snow. These keep feet very warm and the insole is extremely comfortable. No support around the foot as they are a quilt for your foot. The down comes up the ankle, again very warm. I love mine and they cured the cold. OK for going in and out of the house, but not for a long walk.

Functional - Definitely not the sexiest slippers, but very warm and great for running the dog outside in the evening. Not a pair that can just be slipped on real easily, as mine tends to get caught in the top and it has to be held up to get it on right. Also, I didn't find it had the ankle support others mentioned. But overall great for keeping warm this fall and coming winter months.

Space boots in Scotland - Bought these for trip to Scotland. They look like something for an EVA but I loved the way they kept my feet warm and not too hot in the cottage. You can wear them out, say onto the deck. But I wouldn't wear them outside for more than a quick trip to get the post.

These shoes are comfortable and fit well. They run maybe a half size small. I bought them last year for my first grader’s school uniform. The dye job failed early (within a month) and strips of white dye were peeling off. I returned them and exchanged for another pair which made it through the year, but again the white dye cracked and buckled, but only in a few spots this time and not so prematurely. (I used to work in shoe repair, I believe the leather was not adequately prepared before dye application). I will buy them again because I can’t find any other leather, black and white saddle shoes in the toddler size I need for my younger daughter. I am trying a different brand in a larger size for second grade. I hope it was just a bad lot.

Great Slippers! My feet are always cold in the winter. I've tried these slippers alone, my feet end up a little sweaty since the fabric is like a windbreaker. I put on a pair of socks first then pull the slippers on, and they work better than any other slipper I've tried...and I've tried a lot!

I love these - This is the first bootie that really keeps my feet warm. I am handicapped and cannot move my feet like those who can, It has been very difficult to get something that can keep my feet warm and perfect for around the house.

Warmth and cozy too! I am on Cape Cod for the winter (first time in 10 years) and feel the cold all the time, especially in my feet and hands. These Sierra Design Booties are THE BEST thing I have EVER had. I call them my "slipper boots". I wear them to get the morning newspaper and mail and all the time inside. I would HIGHLY recommend them to everyone!!! I also fractured my pelvis 4 years ago, so support in any shoe/boot is of major importance to me!
