Rated 4 out of 5 by from Just what I was looking for These NANOspikes keep your feet closer to the ground and do not feel as much like you have Lego blocks stuck to your feet compared to other solutions. I wear a men's 10.5 shoe and the large fits pretty well. The front portion tends to ride up on the toe and not stay on the bottom of the shoe. Therefore, the front two spikes never come into contact with the ground. I've tried every adjustment I can think of to make sure all the spikes stay under the shoe... not happening. The large would probably be a perfect size for a 11 or possibly an 11.5 shoe. The most important thing is they are the lowest profile traction devices I've found and they work like magic in solid, clear ice. I would definitely buy them again.

Rated 4 out of 5 by from Highly Recommend I bought these one year ago from REI at the beginning of a terrible, icy, not very running-friendly winter in Alaska. The coil style traction devices I was trying to run in weren't cutting it and I was sick of falling! These made a HUGE difference. I am able to maintain a natural running stride on ice, snow, dirt, and sections of dry pavement. They also pack into a compact little carrying case, easy to stash in my hydration pack for long runs of varying conditions. After 3 months of winter training for an ultra, I have noticed no wear and tear. Depending on my shoe choice, sometimes the toe piece will create some uncomfortable pressure on my big toe, or creep over and become cockeyed, so I gave 4 stars, but not enough of an issue for me to consider other traction devices.

Rated 5 out of 5 by from The best I've tried for winter running Admittedly, running is best on dry pavement without having to have anything extra on your feet, but having a pair of these in my bag-of-options often means the difference between no-I-can't-run-today and yes-I-can. They're great on ice or hard-packed snow, not too bad on bare pavement for short distances. They are low-profile enough to allow for a natural stride. They are easy to put on and take off and small enough to take along in a small pack or even a pocket. If you don't like to have to skip runs because of bad conditions, get a pair!

Rated 5 out of 5 by from Excellent on Black Ice on Pavement I bought a set of these in November 2017 for use walking in an urban environment in the winter. These are AWESOME. They are easily attached to your shoe / boot. They are also easily removed from your shoe / boot. These provide excellent traction on black ice on pavement. They are also great for use on hiking trails in icy conditions. I live in New England where ice-events are common. NANOspikes are perfect for these icy conditions. I highly recommend them. In fact, my wife also just bought a pair.

Rated 5 out of 5 by from Excellent for running I've been running throughout the winter using these over normal running shoes. The spikes combined with the rubber soles gives excellent grip on ice and packed snow. Unlike some other traction devices that tend to dig into the boot or shoe, these are designed to fit over less-sturdy running shoes. I've found that I can run for several hours without my toes developing rubbed spots or blisters (as I've had with other traction devices).

Rated 5 out of 5 by from Confidence w/o overkill I use these for hiking and trail running and am very pleased so far. Have enough grip that I feel confident running on icy, snowy trails in the mountains. And these are probably less damaging to the trails than many traction devices that are more aggressive but probably not necessary where the exposure isn't too great. very easy to slip on your shoes.

Rated 5 out of 5 by from Not great for wide feet I bought these for winter trail running in Minnesota. They provide fantastic traction, even in super slippery conditions. I wish I could keep them, but I have wider feet, and the lateral squeeze of the rubber upper over my trail-running shoes became painful on runs longer than five miles.

Rated 3 out of 5 by from Bought these for my wife... I bought these for my wife on the recommendation from one of the sales associates. We use these for walking the dogs around the neighborhood where there are quite a few ice patches on the sidewalks and on the streets. We admit, they do work great on the ice, but it's hard to walk in them if you aren't on ice, if you are walking on the sidewalk without being on ice or snow, it's like walking in soccer cleats. It's a weird feeling and not a great walking experience...

Will these fit full sized hiking boots? I wear 12/12.5

Asked by: Mocnm
Yes, the XL will go up to men's running shoes size 14 so a size 12.5 hiking boot will fit fine.
