The ICEtrekkers Diamond Grip ($40) were one of the most useful pieces of gear I tested on my last trip. They are comfortable under asphalt and work very good on mixed terrain (rocks/ice). They provide great grip and they weight only 311 grams. They seem to be well built. It's the second pair I buy because I lost one of them. I highly recommend them for occasional hiking in slippery surfaces. They are going to be perfect for my thru-hike.
They fit running shoes perfectly but remember to buy the proper size for you shoes.
