Hello Midnight,

The difference is that you need good wrists with forearm-crutches, but they are easyer with daily use.

Underarm crutches are clumsy, but more comfortable when you have not really strong arms

Well in daily use it makes a lot of difference. In the Netherlands (and most of the European countries), you only see forearm crutches.

Well, in that case: Be morse specificic so we can help you, but DON'T answer like you do now if someone is so kind to trie to answer your questions!
