Quick Answer
Replacing worn hobnails on mountaineering boots is a simple DIY fix that restores grip on icy terrain. Use corrosion-resistant tungsten alloy studs and follow a few careful steps to avoid damaging your boot soles.
When to Replace Hobnails
Check your hobnails before every winter outing. If the studs are rounded, cracked, or missing, your traction on ice and hard snow is compromised. Replacing them early prevents slips and extends the life of your boot soles.
Choosing Replacement Hobnails
Not all hobnails are the same. Look for ones made from wear-resistant, corrosion-resistant tungsten alloy—like those originally designed for rally car tires. They screw directly into rubber soles and provide reliable bite on frozen surfaces.
Step-by-Step Hobnail Replacement
- Remove Old Hobnails: Use a flathead screwdriver or a dedicated stud remover to unscrew each worn hobnail counterclockwise. Work slowly to avoid stripping the threads in the boot sole. If a stud is stuck, apply gentle heat with a hair dryer to soften the rubber, but never use a torch—it can melt the sole.
- Clean the Thread Holes: Remove any debris or rubber dust from the empty holes using a toothpick or compressed air. Clean threads ensure the new hobnails seat fully and stay tight. Skipping this step can cause new studs to cross-thread or loosen during use.
- Screw in New Hobnails: Hand-thread each new hobnail clockwise into its hole until snug. Use a screwdriver for the final quarter turn, but do not overtighten—you can strip the rubber threads. Test each stud by trying to wiggle it; a properly seated hobnail should feel solid and not rotate freely.
- Test Traction on a Safe Surface: Before heading onto ice or snow, walk on a patch of hard ground or packed snow to seat the studs and confirm they grip. Listen for clicking or wobbling sounds. If any stud feels loose after testing, remove it and reinstall with a dab of rubber-safe adhesive.
