新手求攀岩鞋及安全带推荐

新手，攀过一次，打算以后多练练，所以先置攀岩鞋，顺便置个安全带，求推荐

平时穿鞋子都是42，大一指，攀岩鞋应该买41码的对么？

攀岩鞋子有粘扣的，系带的，直接滑进去的，这几用有什么特点呢？一般选择哪哪种？

主要考虑以下几款鞋子：
Scarpa Reflex Climbing Shoe - Men's
Scarpa Helix Climbing Shoe - Men's
Scarpa Instinct S Climbing Shoe - Vibram XS Grip2
Scarpa Force X Climbing Shoe - Vibram XS Edge - Men's

La Sportiva Tarantula FriXion RS Climbing Shoe
La Sportiva Nago Vibram XS Edge Climbing Shoe
La Sportiva Mythos Vibram XS Edge Climbing Shoe - Men's
La Sportiva Cobra Vibram XS Grip2 Climbing Shoe
La Sportiva Jeckyl VS Climbing Shoe

安全带考虑以下4款，求推荐
Black Diamond Momentum AL Harness
Black Diamond Bod Harness
Mammut Ophir Harness - Men's
Black Diamond Momentum 3S Harness
