This is my second purchase from Protalus, my first was with the help of the companies advisors. They helped me select the proper insert for my favorite Sketchers sneakers! I am now a subscription customer and find the savings KOOL. I WAS SKEPTICAL OF ONLINE ORDER, BUT AMAZINGLY...I ORDERED ON 5/10 AND I AM WEARING THEM ON 5/14 ! I HAVE AGAIN FOUND THEM TO BE AWARD WINNING COMFORTABLE FOR MY BACK PROBLEMS. THANK YOU, AND I DEFINITELY RECOMMEND! $$$ CAN'T BE BEAT WITH THIS SUBSCRIPTION PROGRAM. T. Y .AGAIN, TRUELY A TRUSTWORTHY OPERATION.
