These are great to put in pocket for emergency. However, the front only spikes make it easy to slip on ice and the front loop is small, even on the ex large and for my husband they keep falling off

These work very well and make them very handy for icy emergencies when m in your pocket. Do size up because the front loop is small and they fall off easily if the loop is not sufficiently far back on the toe of the shoe. Even XL falls off for my husband who has size 11 feet

Pocket-sized running spikes

I've used it several times
True to size

I purchased these as a lighter weight, smaller set of microspikes for winter trail running. I have the popular brand of full coverage microspikes that everyone uses for hiking, etc, which certainly work fine, but are a bit bulky to stuff in my pockets on a run and overkill for the typical winter run (for reference, I'm in CO). Writing a review since I couldn't find any when I purchased. Mostly they have lived up to expectations, but they were finicky to figure out how to get them to stay on. First time out they kept falling off (and no, they are not too big, my shoe size is the upper limit of the recommended size range). Ended up having to go back to the house and sit down and figure out what was going on. They only stay on my shoes if the front chain is hooked behind the first "nub" of the grips on the bottom of my trail running shoes (arcteryx norvans). Hopefully I'll get a better hang of doing this on the fly, as the goal w/ these was to be able to put them on quickly if you transitioned from a packed dirt road, for example, to a trail that needed spikes, etc. But as is, I have to manipulate them a fair amount to sit just right, which is challenging when you are in winter conditions.... Suggest to BD would be to consider making the front toe strap stretchy like the back heel material. Or at least try this out. Wouldn't mind the few extra grams. Regarding the grip - work as expected. Did not miss the back foot spikes. Solid feel on everything except a road that was covered in a layer of solid ice, but that was to be expected.


Sizing Chart

If you're on the cusp of going up a size, size up.


How do we figure out what size would fit our shoes. My husband is a men's 11 and I am a woman 9. Please advise. Thank you Jodi
