Running Gear You've Tried and Hated!

What is the running or workout gear recommended to you that you just flat-out hated?

We all have that one friend who has to have the "it" gear of the moment.  I'm not that person.  I spend hours researching the best socks to run in.

I am a minimalist with my running workouts in general, but occasionally, I will splurge on something highly recommended by a friend.  My last splurge (after hours of research) was my Samsung Gear Fit Pro smartwatch.  I've had it for almost a year now and I think I can confidently say that it was a good purchase for me.

My purchase before that was a set of wireless earbuds.  I still have problems getting them to connect and stay connected.  And when they do stay connected, they don't stay in my ears.  FRUSTRATING!!!  I leave them at home and take the wired earbuds that make me grumble because of the flapping wire when I run.

I'm curious what running or workout gear have you purchased, whether recommended by a friend or not, that did not hold up to your expectations?  No gear is too outrageous or small.  Share your gear fails here!
