Ideal gross profit margin for dropshipping shoes?

Hello. Anyone have benchmark info when it comes to gross profit margins on shoes, particularly running and hiking shoes? On average it's costing about $50-75 to fulfill an order (depending on the product purchased) and the sale prices range from $80-110. I've only been in business for a year and I'm quite anxious to see what the end of year reports will look like. I think I may need to raise prices?
