Certainly my soleus ached for a week the last time i ran a the beach.
Perhaps a bit. There's nothing quite like the soreness from the first run or two without a heel strike
However, in my former life I ran about 30 miles a week with a standard shoe and heel strike, and my calves developed a good bit. The real bonus for me has been the strengthening of the intrinsic muscles of the feet (Free's + daily foot drills) and the lack of knee pain when running.
