Using these Scarpa Manta Tech GTX boots is easy. First, put them on like you would any other boots. Tie the laces tightly to ensure a good fit, especially when you're going to be scrambling on small edges or using semiautomatic crampons. When using crampons, make sure they're properly attached to the boots for safety.
Here are some important things to keep in mind. Don't wear these boots in extremely hot or dry conditions for long periods, as it might damage the materials. Also, avoid dragging them roughly on sharp rocks as it can wear out the sole and the upper part.
For maintenance, after each use, clean the boots with a soft brush to remove dirt and debris. If they get wet, let them dry naturally at room temperature; don't use direct heat like a heater or a hair dryer. Once they're dry, you can apply a leather conditioner to the upper part to keep the suede soft and water - resistant. And regularly check the laces, sole, and any other parts for signs of wear and tear. If you notice any issues, get them repaired as soon as possible.
