When to use it
Says something is worthy of, or good enough for, an action: 信頼に足る人物 (a person worthy of trust). The negative に足りない / に足らない means something is not worth the action, often because it is trivial: 取るに足らない問題 (a trivial problem), 恐れるに足りない (nothing to be afraid of).
Nuance
Formal and mostly written. It usually modifies a noun (信頼に足る証拠). The verbs are limited to evaluation verbs: 信頼する, 信じる, 満足する, 尊敬する, 恐れる, 取る. The negative often sounds dismissive. 取るに足らない is a fixed phrase meaning "trivial".
Compare
に値する is close and also formal: 尊敬に値する. に足る stresses that something meets the minimum standard needed: 信頼に足るデータ (data good enough to trust). に値する stresses that it deserves the action because of its value: 一読に値する本. In the negative, に足らない is much more common than に値しない.
Tip: Memorize two phrases: 信頼に足る (trustworthy) and 取るに足らない (trivial). Most test items use one of them.
