You can reset your Chrome profile settings to defaults at chrome://settings/reset (site won't let me link because it doesn't begin with https://, sorry). This is the simplest version of a Chrome profile reset, but is only accessible via a desktop browser, not directly via Chrome on Android.
This will reset the settings related to your Chrome profile as detailed when you click the button on that page:
This action will:
• Reset some Chrome settings and Chrome shortcuts • Disable extensions • Delete cookies and other temporary site data
It's possible to clear all data associated with your Chrome profile from your Android device at the Google Chrome Sync page. This will erase all of the following:
- Address bar
- History
- Bookmarks
- Reading list
- Open tabs
- Addresses
- Payment methods
- Passwords
- Settings
- Apps
- Extensions
- Themes
Also keep in mind:
Answer from jlehenbauer on Stack ExchangeThis will clear your Chrome and ChromeOS data that has been saved in your Google Account. This might clear some data from your devices. This will also remove your sync passphrase. You can create a new passphrase.

For the record, now there is a Reset button on the flags page.
Manual reset
Flags that can be enabled or disabled have gray font color in their description if set to their default value. The description of altered flags is black.
All drop-down menus should be set to Default or Automatic.
Override
Invoking Chrome with the command-line switch --no-experiments doesn't revert the changes made in chrome://flags, but it ignores them entirely.
