I used pink shoe cleaner that I bought off amazon. Works magic! https://www.amazon.com/Pink-Miracle-Cleaner-Leather-Sneakers/dp/B00A7NDT3A/ref=asc_df_B00A7NDT3A/?tag=hyprod-20&linkCode=df0&hvadid=198098255989&hvpos=1o1&hvnetw=g&hvrand=2257640833856428502&hvpone=&hvptwo=&hvqmt=&a...
took these for my euro trip during summer and an asia trip during winter. Love these shoes. The gum sole on these should be easy to keep clean, but I used the shoe cleaner by pink miracle for the rest of the shoe. Looks A LOT better than what it did, but obviously won't be able to keep these that clean if they're seeing the world.

I use this shoe cleaner on my white sneakers. And I wash the laces in my washing machine with my whites.

Thanks for the recommendation! How is it on midsoles? I've been using this stuff lately and it's been pretty lack luster on midsoles: https://www.amazon.com/Cleaner-Pink-Miracle-Solution-Leather/dp/B00A7NDT3A
I ran into this the other day in amazon... maybe it could help?
