I have one like this: https://www.amazon.com/OPOVE-Sock-Aid-Adjustable-Disability/dp/B094JY2ZLD/ref=asc_df_B094JY2ZLD/?tag=hyprod-20&linkCode=df0&hvadid=533431388350&hvpos=&hvnetw=g&hvrand=12082920520610911829&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9030447&hvtargid=pla-1395547463435&psc=1

pros and cons: it's very helpful for long socks, and is relatively easy to use. it does take a little practice to get used to. However, it really doesn't work that well for the ankle socks I wear in summer. There are lots of versions of it and they're not that expensive.
