Float routing beetwen 2x WS-C4500X-32

I have two  WS-C4500X-32 switches interconnected via 2x Pear 2 Pear connection with different ISPs.

There are two paths setted with different Distance metrics. Therefore when I shutdown the interface with low metric, the routing table don't change automatically to the second link. Anyone could explain better what can be happen?

Remark: The routing table will change only if manually I remove the ip routing wit

MANTS001-DTC#sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
a - application route
+ - replicated route, % - next hop override, p - overrides from PfR

Gateway of last resort is 10.113.138.9 to network 0.0.0.0

S* 0.0.0.0/0 [1/0] via 10.113.138.9
10.0.0.0/8 is variably subnetted, 20 subnets, 6 masks

 

 

MANTS001-DTC#sh run | in route
ip route 0.0.0.0 0.0.0.0 10.113.138.9
iproute 0.0.0.0 0.0.0.0 10.113.138.13 150

STATIC ROUTE:
ip route 0.0.0.0 0.0.0.0 10.113.138.9 <<- why this without egress interface ?

you need to add egress interface additional to next-hop in static route

Hi @MHM Cisco World ,
Thank you for your tip. Here go more details about my scenario proposed. Could you detail more yet your tip?
By what I understood you mean that I should inform from this below declared way, am I correct?
ip route 0.0.0.0 0.0.0.0 tenGigabitEthernet 1/3 10.113.138.9 
ip route 0.0.0.0 0.0.0.0 tenGigabitEthernet 1/2 10.113.138.13 150
