EC90 SL ISA SeatpostThe newly redesigned EC90 SL ISA Seatpost takes our superlight unidirectional carbon and applies our patent pending Independent Saddle Adjustment, allowing for perfect fitment with independent seat angle and fore aft movement. ISA allows you to refine your positioning without needing to undo your rail clamps for each minute tweak. Saddle angle is then locked in place so you have the confidence your saddle will stay put after you find your fit.

Perfect fit! My daughter’s toes just started to reach the toe box on a size 8, so naturally I ordered the size up so she has room to grow and they work wonderfully. Absolutely adorable, shiny and in perfect condition. Glad i got these on sale! Very durable and easy to wipe down. Smells great too! Very flexible for wide feet and great when wearing with socks. She can run and dance; they are non-slip so I feel safe when she’s playing in them.

Love it!

My 3 year old absolutely loves these shoes! True to size, I bought a little bit beigger so they last to summer. She can put them off and on by herself. They are very light. She wears them on sucks and sometimes without. They smell good: ) Design is perfect. She can run in them easily. Highlighly recommend even though price is expensive. But I don't plan to buy any extra shoes for summer but water and sneakers, so it is OK.
