I haven’t been so impressed in a product in a long time as I am with this one. I can not believe the traction these have, even on pure ice! I have never felt so unafraid to walk on ice before!! I would recommend these to anyone who walks in the winter.

I love these NANOspikes so much I've bought two sizes for myself and a pair for my son and tell everyone about them. I generally wear a size 7.5 women's shoe, which is right on the border between XS and S in the NANOspikes. I have an XS to go with my "barefoot" style of Merrell Trail Gloves and just bought an S to go with my hiking boots and larger athletic shoes. I read tons of reviews on both outdoor and running websites before deciding on these spikes. Still, until I could actually use them myself, I was skeptical about my first step on ice. I am extremely pleased to hear the extra "crunch" of the spikes and to feel secure as I walk and run. So yes, if you live in an area with ice, these are the spikes to buy.

These work so well-wish I would of purchased them sooner! Ran 10+ miles today on hard packed snow/ice and never slipped once. As with other reviewers on here, I also noticed how the front seems to press fairly hard into the top of your shoes. I too used them on Altra Timps and stopped a couple of times to try and adjust how they were sitting on my toes. It wasn't bad enough to make me stop running but I may go back to where I purchased them and see if they will let me try a different size. Overall I will still highly recommend these!

These are the best!! Winter running in northern Wisconsin can be a challenge with the snow and icy conditions. I've used my Nanospikes now in multiple conditions without any problems and feel so much more confident. They transition well from ice and packed snow to pavement on partially cleared roads and allow me to run without obsessing about hitting a path of black ice. Highly recommended!

I run 20+ miles a week. I put these on my Altra Timp trail shoes which are well reimforced shoes for trail running. These are not made for running shoes with a mesh top. The rubber straps press in on your toes and you will give up running after a few paces and go home.

These work really well to grip the snow and ice compared to other brands of spikes I have tried. They fit almost seamlessly so it feels like you are wearing shoes with built-in spikes, but they provide the flexibility of using them on different pairs of shoes! Sadly, like a previous reviewer said, I too, get sore toes (from the strap labeled FRONT), though I have tried them with several pairs of shoes on several runs.

Ran 9 miles in these today on the road. (Borrowed my wife’s.). We had three inches of snow over ice. I loved them and just bought a pair for myself. They stayed on and added a little weight but not enough to be concerned. I am a believer!

These are fantastic. I use these for running on icy roads and sidewalks and they are excellent. I am very happy that I did not go with a cheap knockoff but bought these. They are worth every penny. Love these!!!

These work very well for traction on ice when trail running. My problem is, my toes start to hurt after about 3 miles. The top of the device presses uncomfortably on the tops of my toes and I end up with sore toes.
