Grivel Ran Anti Slip Information

Season : AW21

Brand : Grivel

Code : 5064096

The Grivel Ran Anti-Slip spikes are designed for winter runners and walkers on non-technical trails and tracks. They provide traction on snow and ice for any sort of footwear. They're also compact and light, making them a great choice for winter backpackers.

Unlike other 'microspike' traction aids, the Grivel Ran Anti-Slip's have spiked metal plates, which are also articulated.  This means they're fully flexible and compatible with any footwear, no matter how bendy.  Great for running shoes and approach shoes.

Their strong points are: Its ability to adapt itself to different types of shoes, from those for trail running to those for trekking, thanks to the silicone band that requires no adjustment with screws, screwdrivers, or other tools; steel spikes with anti-corrosion treatment; a Velcro band to ensure stability on the foot once fitted. They come with a storage bag too.

While these provide good traction on snow and ice they are not intended as alternatives to crampons in the mountains.  They are intended for non technical terrain only, where the consequences of a slip would not be serious. 

The size chart below is designed as a guide, if you're planning to use these on mountain boots or similar please get the next size up.

  • Size S: 35/38
  • Size M: 39/41
  • Size L: 42/44
  • Size XL: 45/47

  • Grivel Ran Anti Slip Review by Max,  On 19/12/2017 21:36:38

    Seems a well constructed piece of kit and will be carried as emergency equipment . The large sized version fits comfortably on to a pair of Size 43 mountian boots and has the benefit of the velcro tab across the top to help restrain any movement/loosening during wear. Reason of not awarding 5stars is purely because I have not actually had to use yet.
  • Grivel Ran Anti Slip Review by Francis Low,  On 31/10/2019 18:57:56

    Appear well made. Fit firmly to boots and feel very stable when walking. I havent had the opportunity to try them on ice/snow yet, but dont expect any problems. My partner was impressed with them so I got her a set too.
  • Grivel Ran Anti Slip Review by Rosi,  On 06/01/2020 16:03:11

    Very useful and lightweight to carry on the hill in winter when crampons arent needed but you are not sure if there may be some verglas somewhere. Good price from a quality manufacturer but they are a tad small. I had to replace the Medium which fitted my size 41 boot with a Large as I couldnt get them over size 42 boots. Make sure you try in the comfort of your home as it will be doubly difficult in a howling gale on a mountain!

    Got these for my wife as shes a bit nervous walking on snow and ice. She loved them - they gave her lots more confidence. Would definitely recommend.
  • Grivel Ran Anti Slip Review by Paul ,  On 19/01/2021 08:27:29

    Simple, light and highly effective on icy surfaces at low to high elevations. Great for semi stiff walking and trail shoes. I would not use for mountain conditions or with winter boots; theyre not a substitute for 12 point crampons, but excellent for the use described.
  • Grivel Ran Anti Slip Review by Kerry,  On 08/01/2021 22:35:53

    Fab little lightweight item to have in your winter bag. No substitute for full on crampons but does the job if you need something in between. Seem robust enough for light winter conditions. Fits securely onto a variety of shoe size and style.
