Dexter has a unisex THE 9 listed separately and based on that sizing a women size 9 would be a men size 7.5. You may want to try the True Fit Guarantee option too which could help you switch sizes on this same model shoe. To see full details of the True Fit click the "?" out beside this option.

This shoe is an EE width in the wide width version. The standard width version is a D width.

The only shoe on our website wider than an EE width would be this shoe which is an EEE width: https://www.bowling.com/products/linds-mens-classic-black-right-hand-wide-width.htm

They will likely be very similar in fit but the material is a little different and this could give you a slightly different feel. Also if your current shoe has been used for 6 years it will be broken in more and actually may feel a little bigger because of being broken in.

THE 9 shoes have the toe clip to help secure the removable pad to the shoe better than other models so this would help if you drag your toe. However, there are not any shoes that will work well with toe drag. Toe drag will eventually rub any shoe down and break down any of the shoes over time so it is hard to say which one to go to that works best for toe drag. I would say that if you get a shoe that does not have any kind of removable traction pads then that is probably the best option so you may want to go with a shoe that does not have the removable traction soles.
