Hi everyone, I have just got a pair of Therashoes on my physio's recommendation. They are like MBTs but cheaper. Has any one had these? They feel wierd, having a rounded sole, and they really make your muscles work. I only got them this morning, and already my thighs are starting to ache! They are also highlighting how bad my posture and foot position is. I was walking very flat footed and using the outside of my foot, and these are correcting this. So far I am impressed with them!
