Nov 20, 2015 at 18:12 comment added Gerhard Paseman Thanks! I'll check it out. If it looks good and you want some rep, I'll come back and ask you to post your comment as an answer. (You can do that anyway without waiting for me.) Gerhard "Never Thought Of 'Uniform Convexity'" Paseman, 2015.11.20
Nov 20, 2015 at 17:56 comment added Suvrit If you search for stuff related to uniform convexity you'll find examples. For instance, if $1 < p < 2$, under you hypothesis, one can obtain $\|x+y\| \le \sqrt{5-p}$ which is clearly $< 2$; see e.g., web.math.princeton.edu/~naor/homepage%20files/inequality.pdf also, "Hanner's inequality" is a good keyword I think
