Review on ⚡ Nathan Light Spur Grey Size: Illuminate Your Run with Enhanced Visibility by Dennis Reed

First of all, all ratings are based on how well the spur stands up to certain brands/shapes/sizes. At the same time I wear ASICS Kayano shoes in size 9.5. Kayanos are stable shoes, so they tend to be more durable and heavier than many running shoes on the market. My typical runs are 5-10 miles on sidewalks and paved trails. I haven't tried them on more serious trails (although I see no need to use a red turn signal where there are no cars). It is very bright and bright enough in my opinion. Another important point, this spur is basically a plastic band that is held onto the shoe with small spikes and tension. With my shoes, the spur may not stay exactly where I placed it, but slowly "migrate" to a slightly narrower part of the heel. This is not a problem, but should be taken into account. Also these blinkies are great for my ASICS size 9.5 but other than that your mileage may vary.
