I original wore 990 series. The insole itself covers the instep at a higher level. I bought the current repair to replace as they had worn out with use of orthotics. Initially felt ,comfortable and was going to return. Later realized it was because the lack of/ smaller cut insole no longer covered orthotic so felt uncomfortable. Have now switched out insoles and will try out with a workout to see how they do...Notice size difference in picture. The Gray underneath is old insole , Black on top is from,current sneaker.
