Re-emphasizing MagicHour's comment above. Art's Cyclery offers free returns. Order the size you suspect is best, plus the next 1/2 size up. Try them both with your favorite socks, inside on the carpet, no stress or even the slightest damage. Keep the best fit, send the others right back. If you're not sure, always err on the larger size. Roomy toes are happy toes.
