Shimano levers do not feel comfortable for my small hands, period. They are too wide across the hoods. The only thing Shimano does for small hands is to use a shim to shorten the reach to the brake lever from the drop. Unfortunately, most companies are putting Shimano on their bikes.

I use Campy with Modolo Venus handlebars. The bars are designed to shorten the reach from the lever to the bar. They come as small as 34 cm.

The 3T Eva is another bar that is designed to shorten the reach.
