Hi! I'm new to outdoor climbing and find that the most challenging part of a climb is getting there. I currently use day-hikers, but I'm wondering how I can feel more confident on approaches. I find myself constantly lowering my centre of gravity because I'm slipping on loose gravel/dirt and I have to take the approach relatively slow compared to the rest of my group, even with hiking poles. 

1. what shoes do you wear on approaches? 
2. how can I improve my technical skills to feel more confident? 
3. are there any courses I can take or other advice?

Thank you in advance!
