Adjusting the cleats is worth a try. It impossible to make specific suggestions without seeing you on the bike. That's the advantage of visiting a bike shop. They will put your bike in a trainer and observe you pedaling.

There are many other fit adjustments such as saddle (height, fore/aft, tilt), stem (length and rise), handlebar (height, reach, tilt), crank length, and brake lever position.

A good fitter will quickly spot problems. You may need to slide the saddle back and/or swap the stem for a longer one. If you're new to to road bikes, it may take a while to get acclimated, but you shouldn't settle for a poor fit.

Did you buy this bike from a bike shop, and did they set you up on it initially?
