i normally wear British army standard leather combat boots and I managed to find a wide fit pair of gothy looking knee highs on Wish.com for £20 with skulls, and zip up on the side
I wouldn't recommend Newrock for either budget or longevity.
I purchased a pair of knee high Newrock reactors in the late 90's and they died in 2007.
Ever since, I have had friends purchase newrocks and they havent even lasted 1 year with casual use
They have changed the manufacturing process, and for a premium product I feel they are not worth it.
Demonia on the other hand seem really sturdy, my missus has had her platforms for a while now, and even with a bit of wear and tear still serve her to this day.
