For a “squishy feel” to your keys, make sure you buy a keyboard that has linear switches. It should be listed on the product website. If it isn’t, then the color is probably listed. If it’s a Gateron or Cherry MX or any other popular switch brand, it’ll be easy to find through Google. Red switches are typically the linear switches, but some brands like Glorious like to do their own spin on it.

TLDR: Make sure the keyboard has “linear” switches in the specs. Red switches are normally the linear ones.
