To use these Etnies Semenuk Pro MTB shoes, just lace them up tightly for a secure fit. When you're riding, the special outsole tread pattern works great with multi - placement pedals, giving you good grip. Remember to keep the shoes away from sharp objects to avoid damaging the upper. To clean them, simply use a damp cloth to wipe off dirt and mud. Let them dry naturally in a well - ventilated area. Don't put them in a dryer as it may damage the materials. And if you notice the laces are getting worn, replace them to ensure a proper fit.
