Q: Can you use this safely on suede light gray Golden Goose sneakers?

I used it on light brown and baby blue suede shoes with no issues. It didn’t darken them use once a month if u wear a lot. If it’s a shoe with laces do a test spray on the tongue to see if it makes it any darker just in case.

Q: Is it any good for quality suede shoes

Guys ! - The entire line of Saphir products are from France. Those people offer the Cadillacs of shoecare products; and hence, their products aim at people who wear fine shoes likely to be custom. Quality Suede Shoes is one example. However, if you buy shoes at WalMart or wear a similar kind of shoes, then, you buy Kiwi shoecare products. French Saphir Shoecare Products are meant for a few, and Selekt Supply is up to French standards. Au revoir Mom Amis !

Q: Will this product properly protect white, tumbled leather sneakers?

I've used it on white leather sneakers (Veja Esplar). I didn't notice a color change. I used them on white fabric sneakers as well and didn't notice a color change either.
